Starlink vs Iran's Internet Shutdown: The Cat-and-Mouse Game of Satellite Connectivity

When a government decides to flip the kill switch on the internet, people figure it out fast. They tape over security cameras, tape their Starlink dishes to rooftops, wrap them in camouflage netting, and change their Wi-Fi names to something innocuous. They text updates in encrypted apps. They risk their lives to share footage of what's happening.

This is the reality unfolding in Iran right now, and it's rewriting the playbook for how authoritarian regimes control information.

The Iranian government just conducted what's being called one of the most severe internet shutdowns in modern history. For over 120 hours, connectivity to the outside world dropped to about 1 percent of normal levels. Phone lines went dark. Mobile data vanished. The country was essentially cordoned off from global communication. But Starlink? That's where it gets complicated. The satellite internet service is still there, still fighting, still delivering data even though it's under constant electronic assault.

This isn't just a tech story about whether a satellite can beat a jammer. It's about what happens when the infrastructure for controlling information collides with technology designed to be decentralized and resilient. It's about a Trump administration calling Elon Musk to ask if he can help. It's about thousands of Iranians using Starlink dishes as instruments of resistance while their government hunts them down.

Let's dig into what's actually happening, how the jamming works, why Starlink is harder to kill than older internet infrastructure, and what this means for the future of communication during government crackdowns worldwide.

Understanding Iran's Internet Shutdown Strategy

Iran didn't just cut cables and call it a day. The shutdown was surgical and comprehensive. The government severed international fiber optic connections, disabled cellular networks, and blocked SMS and voice calls. What they've been doing since is even more sophisticated: trying to selectively degrade certain types of traffic while maintaining just enough connectivity for essential government operations.

The timing matters. Thousands of people had taken to the streets in anti-government protests. Images and videos of the crackdown were spreading globally. The regime's priority was clear: stop the information flow. Traditional internet infrastructure is relatively easy to kill when you control the physical infrastructure. A few key routers, a few fiber optic cables, and you've essentially isolated the country.

But satellite internet changes the equation entirely. You can't cut a signal coming from space. You can't destroy the infrastructure without a military strike. What you can do is jam it, degrade it, and make it unreliable enough that most people abandon it. That's the strategy the Iranian government has adopted.

What's remarkable is that they're even doing this. A few years ago, satellite internet jamming was something you only read about in military conflict zones. Now it's being deployed against civilians trying to document government violence. That escalation tells you something about how seriously authoritarian regimes take the threat of uncontrolled communication.

According to The New York Times, the Iranian government has been using sophisticated methods to maintain some level of connectivity for government operations while severely restricting public access. This approach highlights the regime's intent to control the narrative by limiting the flow of information to the outside world.

Packet loss reached up to 80% during jamming, making internet activities nearly impossible. Improvements have reduced this to around 10%.

How the Jamming Actually Works

Starlink operates in the Ku band and Ka band frequencies. The satellite signals are relatively weak by the time they reach your dish on Earth, which means they're vulnerable to interference. When Iran's military-grade jamming equipment floods those frequencies with noise, the receiver in your Starlink dish struggles to distinguish the legitimate signal from the interference.

Think of it like trying to hear someone whisper in a loud nightclub. The actual conversation is happening, but you can't make out the words. Jamming creates that effect electronically. The Iranian government is essentially running a nightclub in the same frequency bands Starlink uses.

What's particularly clever about their approach is that they're not trying to completely block the signal. Complete blocks are harder to achieve and easier to notice. Instead, they're introducing selective degradation. Uploads are hit especially hard. Video is difficult to transmit. But text-based data might still get through. This strategy makes the connection appear "working but terrible" rather than completely broken, which can actually be more effective at discouraging usage.

According to reports from IranWire, the initial packet loss rates were between 30 and 80 percent. That's not just slow. That's almost unusable. At 80% packet loss, your device is losing four out of every five data packets. Imagine waiting eighty percent of the time and getting data ten percent of the time. It's maddening.

The good news is that Space X engineers apparently started working on this problem immediately. They weren't waiting for the Trump administration to call and ask them to do something. Nas Net reported that after collaboration with Starlink's technical team, they managed to reduce packet loss down to about 10 percent through software updates and signal adjustments. That's not perfect, but it's the difference between nearly unusable and actually functional.

But here's the critical part: Nas Net described this as "an ongoing game of cat and mouse." Space X finds a way to get around the jamming, and Iran's military adjusts their equipment to jam more effectively. Then Space X adapts again. It's a cycle that could continue indefinitely, with neither side achieving total victory.

Initial packet loss due to jamming was between 30% and 80%, but technical interventions reduced it to about 10%, significantly improving usability. Estimated data.

Why Starlink Is Harder to Kill Than Traditional Internet

Before satellite internet existed, shutting down a country's connectivity was actually pretty straightforward for a government with physical control over infrastructure. You control the telecom companies. You control the data centers. You control the fiber optic cables running in and out of the country. Flip a few switches, and you've isolated the population.

But Starlink operates under a fundamentally different architecture. The service doesn't depend on a single point of failure. There's no central Iranian router that controls access. There's no telecom company executive the government can threaten into compliance. The satellite constellation is owned and operated by a company on the other side of the world. Each user's dish is essentially its own gateway to the global internet.

This is why jamming is the government's only real option. They can't cut the connection because there's nothing to cut. They can't arrest the infrastructure because it's in orbit. They can only fight signal with signal, electromagnetic noise with electromagnetic noise.

That said, jamming has been effective enough to make the service unreliable. The game hasn't swung completely in Starlink's favor. It's not like Iranians suddenly have perfect internet while the government watches helplessly. The government's countermeasures have worked well enough to significantly degrade the service.

But the asymmetry is important. For a government to jam Starlink effectively, they need to maintain constant, energy-intensive electronic warfare. It's not a one-time action. It requires continuous effort and resources. For Space X, fixing the problem might just be a software update that gets pushed to thousands of dishes simultaneously. The economics favor decentralized, resilient infrastructure over centralized control.

The Political Dimension: Trump, Musk, and Iran

Here's where the story gets interesting from a geopolitical perspective. Trump called Elon Musk and asked him to help get Starlink working more reliably in Iran. The White House confirmed the conversation happened. This is not a normal interaction between a U. S. government and a private company. This is the President of the United States directly intervening in a technical problem to help people communicate in a country where the government is conducting a violent crackdown.

The politics here are layered. The Trump administration is explicitly siding with Iranian protesters against the Iranian government. They're using a private company to project American influence into a geopolitical conflict. Musk, who loves the spotlight, has publicly committed to getting Starlink working in Iran. Space X is apparently already working on technical solutions.

But it's also worth noting that this intervention serves multiple purposes. Allowing Iranians to communicate benefits protesters and dissidents. It's good for Starlink's image as a freedom-protecting service. It's good for the Trump administration's credibility on supporting human rights and democracy. And for Musk, it positions Starlink as a geopolitical tool that can do things traditional government infrastructure can't.

The Biden administration had already paved the way for this in 2022, issuing a general license allowing U. S. companies to make internet services available to Iranians. But having the sitting President explicitly champion Starlink as a solution to government internet shutdowns takes it to a new level.

From Iran's perspective, this is infuriating. The service is technically illegal to possess or use in the country. The government has been actively searching for and confiscating Starlink dishes in Tehran. Now they're dealing not just with individual activists using the service, but with the open support of the U. S. President and one of the world's most prominent tech entrepreneurs.

How the Jamming Affects Different Types of Data

Not all internet traffic is equally vulnerable to jamming. This is a crucial detail that affects what information can actually get out during a shutdown.

Video is the most bandwidth-intensive type of data. A single video upload from a smartphone can be tens or hundreds of megabytes. When packet loss is 30-80 percent, getting a video completely uploaded to the internet becomes incredibly difficult. You might need to try twenty times to get one video through successfully. This explains why the Iranian government specifically targeted uploads in their jamming strategy. They wanted to prevent videos of the crackdown from being shared globally.

Text messages and images are more resilient. A text message is tiny, only a few kilobytes. Even with high packet loss, text can get through by resending repeatedly. Images are larger but not as demanding as video. This creates a hierarchy of what information can escape during a shutdown.

That's why you see people using encrypted messaging apps to send text updates about what's happening, even when video streaming would be impossible. A message saying "military presence reported at this location" takes seconds to send even with high packet loss. A five-minute video of that military presence might need fifty attempts to upload.

Space X appears to have tuned their system to prioritize different types of traffic differently. If you're familiar with Quality of Service optimization in networking, you understand the principle. You give different priority levels to different types of data. If the jamming is preventing video uploads, maybe the system redirects video users to text-based alternatives. Maybe it suggests uploading to platforms that compress video more aggressively.

This cat-and-mouse game extends to the technical level. Iran's engineers are trying to jam broadly. Space X's engineers are trying to find pathways through the jamming that work for the most critical information. It's a technical battle happening in real-time with serious political consequences.

Starlink's Growing Role as a Lifeline During Government Crackdowns

Before the current crisis, Starlink had already become known as a tool for bypassing internet censorship in countries with restrictive regimes. But the scale of what's happening in Iran is unprecedented. According to a fundraising page set up to help get Starlink terminals to Iranians, over 100,000 people in the country are already using the service to bypass censorship.

That number is significant for multiple reasons. First, it shows the appetite for uncensored communication is massive. People will seek out and pay for access to services that connect them to the outside world. Second, it shows that Starlink has achieved sufficient market penetration in Iran that it's become a meaningful alternative to government-controlled infrastructure.

Before the latest crackdown, using Starlink was already technically illegal but somewhat tolerated. People quietly used it. The government probably could have done more to root it out, but they didn't. It wasn't until the protests became serious and the government decided information control was critical that they started aggressively confiscating equipment.

What's remarkable is that even with aggressive government action, the service persists. You can't shut down all 100,000+ users simultaneously. You can't arrest everyone with a dish. You can jam the signal, but you can't eliminate the physical infrastructure overnight without causing massive collateral damage or admitting defeat.

This has created a new situation for governments worldwide that want to control information during crises. You can't fully shut down Starlink. You can only degrade it. And if your population is motivated enough to accept degraded service, it's still better than nothing.

Starlink's decentralized architecture makes it harder to disable compared to traditional internet, which relies on centralized control. Estimated data.

The Economics of Internet Shutdowns in the Satellite Era

Governments have historically conducted internet shutdowns because they were relatively cheap and straightforward. You control the infrastructure, you flip the switch, people have no way out. The economic cost was just the loss of business for internet service providers, which is something the government probably didn't care about anyway.

But Starlink changes the economics. If a significant portion of your population can access the internet through satellite no matter what you do, then shutting down traditional infrastructure doesn't achieve the goal of information control. It just forces people to use the satellite alternative. And once they're using that, they might discover it actually works better. It might not even be that much more expensive.

That's a serious problem for governments that rely on information control. It makes the shutdown strategy less effective. It means they have to invest in jamming technology, which is expensive and requires ongoing resources. It means they have to deal with the public relations problem of admitting they need military-grade electronic warfare to prevent their citizens from accessing information.

Iran's government isn't the first to face this. Russia has dealt with it during their invasion of Ukraine. China has had to deal with Starlink interference despite their comprehensive domestic censorship infrastructure. The problem is growing as Starlink's constellation expands and satellite internet becomes more prevalent globally.

From a long-term perspective, this might represent a fundamental shift in the balance of power between governments and populations. Control over internet infrastructure used to be simple because infrastructure was localized and centralized. Satellite internet is neither. That's not to say governments can't adapt. But they're going to have to get creative, expensive, and technically sophisticated.

How Protesters Actually Use Starlink Under Jamming

It's worth understanding the practical reality of what people in Iran are actually doing with these degraded connections.

First, they're using VPNs and encrypted messaging apps. The jamming makes the connection slow and unreliable, but encryption still works. If anything, the unreliability incentivizes better security practices because you know the government is actively trying to intercept your data.

Second, they're using low-bandwidth alternatives. Instead of video calls, they're using voice calls or text. Instead of uploading full-resolution photos, they're using heavily compressed images. Instead of streaming information in real-time, they're using queued uploads that might take hours to complete but eventually get through.

Third, they're using distributed networks and alternative protocols. Someone somewhere is going to get a message or image through. That person then forwards it to others. The message bounces around through whatever channels are available until it reaches the global internet. It's inefficient and slow, but it works.

Fourth, they're being creative with equipment. Starlink dishes are being mounted in creative locations. Some are being rotated to find better signal angles. Some are being moved between locations to test where the jamming is weakest. People are essentially doing signal engineering to find the least jammed pathways.

Nas Net's advice was specific: "Don't forget physical camouflage, hiding the Starlink IP, and changing the wireless network name!" That's the reality of using this technology in a hostile environment. You're hiding the physical device. You're masking your internet identity. You're making your network invisible to casual observation.

For many people, even degraded satellite internet is better than the alternative of complete isolation. A connection with 30 percent packet loss is unusable for most purposes, but if it's your only connection to the outside world, you'll figure out how to use it.

Text messages are the most resilient to jamming due to their small size, while video uploads are the most affected due to high bandwidth requirements. (Estimated data)

Free Starlink as a Geopolitical Tool

Early in the crisis, Nas Net announced that after weeks of negotiations with Starlink and U. S. authorities, they had managed to make Starlink service available for free to Iranians. No subscription required. You get a terminal, you turn it on, and you have internet access.

This is a significant move. Before, cost was a barrier to adoption. The Iranian government had used banking sanctions to make it "extremely difficult" for users to pay Starlink subscriptions. Now that barrier is eliminated. It's not just that the service is theoretically available. It's being actively provided for free by organizations specifically trying to help Iranians stay connected.

This changes the game substantially. Before, Starlink was something wealthy or tech-savvy Iranians could potentially get. Now it's being placed in people's hands without cost barriers. That doesn't mean everyone suddenly has unlimited connectivity. The jamming is still degrading service. But it means access is theoretically available to everyone, not just those who can afford subscriptions and figure out workarounds for banking restrictions.

From a geopolitical perspective, this is what we might call "internet freedom as a policy tool." The U. S. and allied organizations are explicitly using technology to support Iranian protesters against their government. It's not subtle. It's openly acknowledged. Both sides understand what's happening.

For the Iranian government, this is infuriating because they can't really stop it without extreme measures that would draw international condemnation. They can jam the signals, but they can't cut off the satellite. They can confiscate dishes, but more are being sent. They can make the service expensive, but now it's free. They can arrest people for using it, but the technology has become so distributed that enforcement becomes nearly impossible.

The Technical Evolution: How Starlink Adapts to Jamming

Space X's engineers have decades of experience with signal resilience, redundancy, and error correction from their work on rocket guidance systems and space station communications. That expertise is directly applicable to the jamming problem in Iran.

The most obvious adaptation is software updates to the receiver firmware. The Starlink dish itself is a piece of hardware, but its behavior is governed by software that can be updated remotely. That's one reason Space X was able to reduce packet loss from 30-80 percent down to 10 percent relatively quickly. They pushed updates that improved how the receiver handles degraded signals.

These might include things like improved error correction algorithms, better frequency-hopping patterns, or different modulation schemes that are more resistant to jamming. These are highly technical adjustments that most users would never notice or understand, but they directly affect how well the system functions under jamming conditions.

Another approach is spatial diversity. Starlink operates hundreds of satellites at any given time over Iran. If one is being jammed more effectively, the system can try to switch to communicating through a different satellite with a better signal. This requires coordination between the ground station software, the satellite constellation management, and the user terminals. It's complex, but it's doable.

The company might also be using frequency agility, shifting away from frequencies being heavily jammed toward other parts of the spectrum that are less targeted. This is a technique used in military communications for decades.

Space X might also be working on beamforming and other advanced signal processing techniques. Instead of transmitting the same signal to all users, the system could theoretically focus energy on Iranian users in a way that's harder to jam. This would require coordination with the satellite constellation and would be computationally intensive, but it's theoretically possible.

What's clear is that this is not a static situation. Both sides are innovating. Iran's jamming is getting more sophisticated. Space X's defenses against jamming are improving. The advantage will likely swing back and forth depending on who adapts faster.

Starlink's software updates and technical adaptations have significantly reduced packet loss from an initial 80% to around 10% under jamming conditions. Estimated data.

International Response and Support Networks

What's interesting about the Starlink crisis in Iran is the international response. This isn't just Space X and Iran fighting it out. Multiple organizations have gotten involved.

Holistic Resilience, a U. S.-based nonprofit, has been providing analysis and support. Their executive director, Ahmad Ahmadian, told media outlets that the Iranian government is using "military-grade jamming tools" to specifically target video and content uploads. His presence in the conversation shows this has become an issue that international human rights and digital rights organizations take seriously.

There's also Quilty Space, a consulting firm focused on space policy, providing analysis to policymakers and media about what's actually happening. Their director, Kimberly Burke, provided the insight that you don't need a complete kill switch to cripple satellite internet. You just need to make it unreliable enough. "Think intermittent dial-up speeds," she said, which is a useful analogy for people trying to understand what 30-80% packet loss actually feels like.

Net Blocks, an internet monitoring organization, has been providing real-time data on Iran's connectivity levels. They've been documenting that while Iran's general internet connectivity has dropped to about 1 percent of normal, Starlink access remains patchy but present. That data is crucial for understanding what's actually happening versus what governments claim is happening.

Cloudflare, the global content delivery network, has also been monitoring the situation. Their analysis showed internet traffic from Iran dropped to essentially zero after the initial shutdown, with only minimal variations since. This provides independent verification of how severe the shutdown actually is.

What's remarkable is how much of this information is becoming publicly available. A few years ago, this kind of detailed analysis of a government internet shutdown might have been closely held by governments and intelligence agencies. Now it's publicly discussed, analyzed, and shared. That transparency itself makes it harder for governments to conduct information control without international scrutiny.

The Broader Implications for Internet Freedom

What's happening in Iran is becoming a template for how people resist internet shutdowns in the future. It's showing that satellite internet, while not a perfect solution, is a viable alternative to government-controlled infrastructure when the motivation is high enough.

This has ripple effects globally. Other authoritarian regimes are watching. Some are probably beginning to plan their own jamming capabilities in case they need them. Others are realizing that traditional internet shutdowns might not be as effective as they once were.

For democracies, the lesson is different. It shows that reliance on centralized internet infrastructure can be dangerous. If a government can shut down the entire country's internet just by controlling a few key pieces of infrastructure, that infrastructure is a vulnerability. Distributed, decentralized alternatives provide resilience.

This might actually drive investment in diverse connectivity options, including satellite internet. Countries might start encouraging satellite internet adoption specifically because it provides resilience against shutdowns. What was once seen as a niche service for rural areas might become strategic infrastructure for urban areas too.

The other implication is that internet access during crises is becoming recognized as a human right in some contexts. The Trump administration explicitly supporting free Starlink access in Iran is an acknowledgment that preventing information flow during government violence is so serious that external actors have a justification for supporting alternatives.

That's a significant shift from even a few years ago. It means that if other governments attempt internet shutdowns during crises, they might face not just domestic pressure but international pressure and support for alternative solutions.

Challenges That Remain

Despite all the optimism about Starlink as a solution, significant challenges remain.

First, the jamming is effective enough to make normal use difficult. You can't stream video. You can't use most applications smoothly. You can't conduct video calls. The service exists, but it's marginal. It's useful for sending text and images, but not much more.

Second, the Iranian government controls physical access. They're actively searching for and confiscating dishes. If they increase enforcement, they could significantly reduce the number of active terminals. You can't use Starlink if you don't have a dish, and you can't get a dish if the government catches you receiving it.

Third, there's the question of sustainability. How long can the game of cat and mouse continue? Will Space X keep pushing updates to deal with jamming? Will Iran continue to invest in jamming, or will they move on to other forms of information control? There's no guarantee this remains a viable channel indefinitely.

Fourth, the free service model is dependent on continued international support. If the organizations providing free access lose funding or political support, users might have to pay again. The cost barrier comes back.

Fifth, there's the technical reality that even with improvements, the service is degraded. Nas Net described it as "an ongoing game of cat and mouse; therefore, conditions may change again or even worsen." They're not claiming victory. They're claiming the situation is unstable and could deteriorate.

These challenges don't negate what Starlink is accomplishing. They just recognize that this is a partial solution to a serious problem, not a complete solution.

What This Means for the Future of Connectivity During Crises

The Iran situation is probably going to be studied for years as a case study in how governments attempt to control information and how distributed technologies complicate that control.

One clear lesson is that centralized infrastructure is vulnerable. Countries that rely entirely on traditional ISP infrastructure can be cut off relatively easily. Countries that have diverse connectivity options, including satellite, maintain at least some communication capability even during shutdowns.

Another lesson is that jamming, while effective, is not a complete solution. You can degrade satellite internet significantly, but you can't eliminate it entirely without military action. That's a different calculation than traditional shutdowns, where you flip a switch and everything stops.

A third lesson is that external support matters. Without U. S. government backing, free Starlink service, international attention from monitoring organizations, and nonprofit support, the situation would look different. Isolated countries might be more vulnerable to complete shutdowns if they don't have these external support networks.

Looking forward, this probably accelerates investment in satellite internet globally. Space X has competition from companies like Amazon's Project Kuiper and others. These companies will see the Iran situation as validation that their services have real demand, not just in rural areas but in contexts where communications infrastructure is threatened.

It also probably accelerates investment in jamming technology by governments that feel threatened by uncontrollable communication channels. This is an arms race of sorts, and both sides will keep developing new capabilities.

Ultimately, what's happening in Iran represents a transition point in how information flows during government crises. The era of complete internet shutdowns might be coming to an end, replaced by increasingly sophisticated attempts at partial control through jamming, censorship, and other techniques. But the era of complete information isolation is probably over, at least for populations with access to satellite connectivity.

The Role of Public Opinion and Information Warfare

One element that's critical to understand is that this isn't just about technology. It's about the information battle for global public opinion.

When videos of government crackdowns get out, they affect how the world perceives Iran. They affect international pressure on the regime. They affect the morale of the protesters themselves. Information is power, and the ability to control what information leaves the country is strategically significant.

By attempting to shut down internet access, the Iranian government is essentially trying to prevent the world from seeing what's happening. By supporting Starlink access, the U. S. and international organizations are trying to ensure the world can see it. This isn't just about individual Iranians staying connected. It's about the global information ecosystem.

That's why the government is targeting uploads specifically. Video of protests spreading globally is more powerful than a text message about protests. The government is trying to prevent the powerful information (video) from escaping while maybe accepting that some weaker information (text) will get through.

The information warfare dimension explains why the Trump administration is getting involved directly. It's not just about helping protesters. It's about winning the battle for how the world perceives Iran and its government. It's about positioning the U. S. on the side of information freedom and human rights, at least in this specific context.

Both sides understand these stakes. That's why the effort on both sides is so intense, so technical, and so immediate.

FAQ

What is packet loss and why does it matter during jamming?

Packet loss refers to data packets failing to reach their destination. When the Iranian government jams Starlink signals, they're causing 30-80% of data packets to fail transmission. At 80% packet loss, you lose four out of every five data packets, making most internet activities impossible. Even basic web browsing becomes nearly unusable, though text messages might still get through eventually.

How is the Iranian government jamming Starlink?

Iran is using military-grade jamming equipment to flood the Ku and Ka band frequencies that Starlink uses with electromagnetic noise. This is similar to trying to hear someone whisper in a loud nightclub. The jamming doesn't completely block the signal but degrades it severely, particularly affecting uploads and video data which require consistent, strong connectivity.

Can Starlink completely bypass the jamming?

Not completely, but Space X has made significant improvements. Nas Net reported reducing packet loss from 30-80% down to approximately 10% through software updates and technical adjustments. However, this is described as an ongoing game of cat and mouse, meaning conditions can change as both sides adapt their techniques. The service remains partially functional but degraded.

Why is Starlink illegal in Iran?

Starlink is illegal in Iran because the government has never authorized the service to operate and does not have regulatory control over it. Satellite internet services that bypass government infrastructure are viewed as threats to state control over communication and information. The government has actively confiscated dishes and banned the service.

How many people in Iran are using Starlink?

According to fundraising pages supporting Starlink access, over 100,000 people in Iran have been using the service to bypass government censorship even before the latest crisis. The free service announcement from Nas Net suggests this number could potentially expand significantly if access barriers are removed, though the jamming and government confiscation efforts limit practical growth.

What advantage does satellite internet have over traditional internet infrastructure?

Satellite internet has a fundamental architectural advantage: there's no central point of control. Traditional internet shutdowns work by controlling the few major providers and data centers. Starlink operates through thousands of satellites in orbit, and each user's dish is essentially its own gateway to the global internet. Governments cannot simply flip a switch to disable it, though they can jam the signals with difficulty and expense.

Is video content affected more than text content?

Yes. Video requires much more bandwidth and is more sensitive to packet loss than text. At 30-80% packet loss, video uploads and streaming become nearly impossible. Text messages, being much smaller data payloads, can often get through by retrying multiple times. This is why the Iranian government's jamming specifically targets video and upload capabilities while some text-based communication remains possible.

How are protesters using Starlink despite jamming and government enforcement?

Protesters are using encrypted messaging apps, VPNs, and low-bandwidth alternatives like text and heavily compressed images. They're physically camouflaging dishes, hiding Starlink IP addresses, and changing wireless network names to avoid detection. They understand that even degraded connectivity with 30% packet loss is better than complete isolation when information needs to get out.

What role is the U. S. government playing in supporting Starlink in Iran?

The Trump administration explicitly asked Elon Musk to improve Starlink reliability in Iran and publicly committed to supporting the service. The Biden administration had previously issued a general license allowing U. S. companies to provide internet services to Iranians. Organizations like Nas Net have negotiated with both Starlink and U. S. authorities to provide free access, removing cost barriers for Iranian users.

Could other governments use the same jamming technique?

Yes, other authoritarian regimes are likely studying Iran's approach. Military-grade jamming technology is not new and could potentially be deployed by other governments wanting to control satellite internet access. This has implications for internet resilience globally and might drive countries to invest in redundant connectivity options and more sophisticated signal processing to resist jamming.

What is the long-term outlook for Starlink in Iran?

The situation remains uncertain and is described as an ongoing game of cat and mouse. While Starlink cannot be completely eliminated, the jamming is effective enough to make most uses difficult. Long-term success depends on whether Space X can continue adapting faster than the Iranian government, whether external support for free access continues, and whether the government intensifies physical confiscation efforts. The service provides a partial solution but not a complete one.
