A Hackers Guide to Circumventing Internet Shutdowns
Cooper Quint · 2026-05-12 · via Electronic Frontier Foundation

Internet shutdowns are devastating for human rights. When people are disconnected from the internet and digital services, it impacts all aspects of their life—from accessing essential information, to seeking medical care, or communicating with loved ones, both in that country and externally. But on January 8th, 2026, the government of Iran shut down internet communications for the entire country as a rebellion threatened to topple the authoritarian government. The government then proceeded to execute as many as 656 dissidents over the next 3 months, though the actual number could be much higher. Which is part of the point: shutdowns often precede government acts of violence. 

Iran’s shutdown was hardly an isolated incident. Earlier this month, the U.S. military invaded Venezuela and kidnapped the Venezuelan president shortly after US cyber forces shut down all internet access and power grids for the capital city of Caracas. India routinely shuts off internet access in the Kashmir region, and Syria shut down internet communications as many as 73 times, most recently in 2025. Even the UK recently had a localized temporary internet shutdown. At the time of this writing there are 14 ongoing internet shutdowns worldwide.  

Government shutdowns aren’t the only reason an entire region or country might lose internet access. Hurricanes, earthquakes, and wildfires can take out internet connections in many regions of the world, and will only increase as climate change ramps up. They can completely disable the communications infrastructure relied upon by victims, their families, first responders, and disaster relief efforts. Having an alternate way to communicate in such times can save lives.  


One way to limit the impact of such shutdowns is to prepare in advance by setting up systems and structure for circumvention and resiliency. 

To keep people connected during internet shutdowns and blackouts, communication networks must be operational before and after the disaster or shutdown. To be effective, they must be widespread so that people can get access to them reliably, and they must be usable by a majority of the community. And any viable solution must be accessible and sustainable on a community level, not just to people with vast financial resources or technical knowledge. You shouldn’t have to be a tech wizard to be able to communicate with your neighbors!

Radios

There are many ways for a community to build their own disaster resilient communications. Radios, for example, are cheap, decentralized, and resilient. Many people with moderate technical skill have set up Meshtastic repeaters. Meshtastic is a way to use a common unlicensed radio spectrum and a technology called LoRA to have peer-to-peer decentralized communications with people in your neighborhood or city. When you buy a Meshtastic device (cheap ones cost around $20) you can link it to your phone and send text messages to people in your area without ever touching the telephone network or the internet. Messages are delivered directly from person to person over public radio waves.

There is also amateur radio, also known as ham radio, which has been used in disaster communications for decades. Ham radio requires a license, but allows you to communicate farther than Meshtastic, using repeaters or even bouncing signals off the stratosphere to talk to people on the other side of the planet or even on the International Space Station. It is even possible to access the internet over ham radio. 

Peer-to-peer messaging apps 

Another option for internet communication during a shutdown is peer-to-peer messaging apps. One such project,called Briar, uses the Bluetooth functionality on phones to route messages from device to device until they reach their destination, even in instances where there is no internet. However, Briar faces the same problems many mesh projects do: almost nobody has the app installed and it’s difficult to use. If a mesh chat app isn’t already widely installed before an internet shutdown, it’s going to be even harder to get people to install it en masse once the shutdown starts. 

A similar effort called bitchat has recently gained some attention. Bitchat is a peer-to-peer chat system that routes over Nostr, Tor, and Bluetooth. It is unfortunately tainted in many people’s eyes by being a project by former Twitter CEO Jack Dorsey, but it is open source and runs on both Android and iOS. It was used with some success in Iran during the latest internet shutdown

Another option is Delta Chat, which uses PGP for encryption and email for routing, while still being much simpler to use than either technology. Delta Chat is highly regarded in Iran for its ability to route a message through even the tiniest sliver of email access.

Satellite internet 

Satellite internet is an internet connection that uses a connection to a satellite dish to reach the internet, such as Starlink. Since there are no wires and no physical connection to infrastructure, satellite internet is harder to shut down. Satellite internet has therefore been used in many cases to circumvent internet shutdowns, with people sharing bandwidth with their neighbors. Satellites are harder for governments to shut down unilaterally.  Unfortunately when the satellites are owned by tech oligarchs, such as Starlink (owned by Elon Musk), or by allied governments, the owners of those satellites may willingly shut down the network anyway. 

Dreaming of a better future

Ultimately an app that is already widely being used would be the best option for shutdown resistant communication. Imagine if WhatsApp or Signal could fall back to mesh networking over bluetooth or wifi. Even better, imagine if our phones all had LoRA built in so we could have more effective mesh networks! What if our phones all had a connection to a satellite constellation run by an international coalition of hackers? We can dream of a better world and we can build it. 

We can’t rely on tech oligarchs to save us, especially when these same companies and governments are the ones to sever our access to the internet and telecommunications. This is why it's important to set up communication mechanisms before a disaster happens. 

As hackers, it's important for us to build these tools and infrastructure of decentralized communication, to help people learn how to use them, and to set up networks before disaster strikes. Get together with others in your city and start setting up resilient off-grid networks and building community now. 

Before you download or use any of the tools mentioned in this guide check with a lawyer in your jurisdiction or country and make sure you understand what legal risks you might be taking on.
