Internet Shutdowns: How Governments Disable Connectivity

On January 25, 2011, Egypt's internet went almost completely dark. Within hours, around 90% of the country lost connectivity. For 18 days, millions of people could not access email, social media, or news websites. The Egyptian government had made phone calls. That was the technical trigger for one of the most dramatic internet shutdowns in history. This was not a cyberattack or a natural disaster—it was a deliberate choice made through channels that look mundane to an outsider but represent enormous power over information.

Internet shutdowns are not rare. Between 2016 and 2024, governments ordered shutdowns more than 1,500 times, according to data tracked by KeepItOn, a coalition that documents these events. Yet many people do not understand how this is technically possible, or why it is so easy. The internet is designed to be resilient and decentralized; how can it be switched off so completely? The answer lies in understanding the physical and organizational infrastructure that connects your device to the rest of the world.

The Role of Internet Service Providers

Your connection to the internet travels through a company or government agency called an Internet Service Provider, or ISP. When you open a web browser, your request goes to an ISP's servers, which forward it onward to its destination. The ISP is the gatekeeper. A government does not need to hack anything or deploy advanced technology. It can simply pick up the phone and order the ISP to stop routing traffic.

In Egypt in 2011, the government contacted the four major ISPs and told them to disconnect. Engineers at those companies disabled routing—the instructions that tell data packets where to go. The internet did not disappear; the infrastructure was still there. But data had nowhere to go. It is like a postal service stopping mail delivery by telling postal workers to stop sending letters, not by destroying the mail trucks or roads.

What made this possible? In most countries, especially those with state control over telecommunications, ISPs are owned by the government or heavily regulated by it. The government is not negotiating with independent businesses; it is ordering its own agency or a company that depends on government licensing. Refusal is difficult and risky for company leadership.

Border Gateway Protocol Withdrawals

Governments also use a more technical method called a BGP withdrawal. BGP stands for Border Gateway Protocol—it is the system that tells routers worldwide how to find each other, like a global telephone directory for the internet. When a country withdraws its BGP routes, it tells the world's routers: "Stop sending traffic to our IP address ranges." Traffic destined for that country gets lost because routers have no directions to deliver it.

This method is particularly effective for countries with a small number of international connections. Myanmar in 2021 used this technique during a military coup and subsequent crackdown on protests. The disconnection did not require military personnel to cut physical cables or coerce every ISP individually. A few commands from the country's internet registry—the organization that manages its IP address space—were enough to make the country unreachable from abroad. However, even during a BGP withdrawal, people inside the country can sometimes still reach each other if they are on the same ISP or connected through local networks.

Mobile Network Suspension Orders

Many people access the internet primarily through mobile phones. Governments can shut down mobile networks separately from fixed-line internet. A suspension order tells telecom companies operating cellular networks to power down or disable data services. Sudan in 2023 saw near-total mobile internet shutdowns during armed conflict, leaving millions unable to communicate via phone or data. This method is effective because mobile networks are even more centralized than fixed-line ISPs; a few large companies control the vast majority of mobile access in most countries.

Throttling and Degradation

Complete shutdowns are obvious and disruptive. Some governments use a more subtle approach: throttling. They do not stop the internet entirely; they slow it down to unusable speeds. Data still flows, but so slowly that loading a single webpage takes minutes. Streaming video is impossible. Messaging apps become unreliable. In practice, throttling creates many of the same effects as a shutdown—people cannot communicate effectively—but it is harder to prove and easier to deny. Authorities can claim technical problems or increased load.

Thailand and Pakistan have both used throttling, sometimes paired with blocking of specific social media platforms, during periods of political sensitivity.

Why Governments Do This

According to KeepItOn data, shutdowns cluster around elections, protests, exams, and security crackdowns. The stated reasons vary: preventing cheating during national exams, stopping the spread of misinformation, or suppressing coordination of protests. These stated reasons deserve skepticism. The actual pattern shows that shutdowns almost always occur when governments face challenges to their authority. During the 2016 elections in Uganda, the government shut down social media. During protests in Venezuela and Hong Kong, internet access was restricted. In India, shutdowns have been used to suppress separatist movements and during religious tensions.

The Technical Simplicity and Economic Cost

A national internet shutdown is technically straightforward. It requires no sophisticated hacking or advanced weapons. A few phone calls or commands can do it. But simplicity does not mean it is costless. Shutdowns damage the economy. Businesses cannot operate. Banks cannot process transactions. The World Bank estimated that the 2016 shutdown in Uganda cost the economy $55 million in a single day. Yet governments choose to pay this price when they believe the political benefit outweighs it.

This reveals something important: internet shutdowns are not accidents or technical failures. They are deliberate acts of policy, calculated trade-offs made by governments that prioritize short-term political control over economic output.

Understanding internet shutdowns helps explain how power works in the digital age. The internet appears borderless and decentralized until you realize that in each country, a small number of organizations control the on-and-off switch. Geography and politics still matter. The next step in understanding this landscape is learning about censorship and content filtering—shutdowns' less visible cousin—and how some people use VPNs and other tools to maintain connectivity when shutdowns occur.
