Iran’s nationwide internet shutdown has surpassed 130 hours, entering its sixth day as tensions continue to escalate across the country. The near-total blackout, imposed on January 8, is widely seen as an effort by authorities to suppress anti-government protests and prevent information from reaching the outside world.
An internet shutdown typically involves restricting access for users, blocking specific platforms, or cutting connectivity altogether. One of the most effective methods is blocking IP addresses, which disrupts the internet’s routing system and isolates users from the global network. In Iran, this process is facilitated by the government’s firm grip on telecommunications infrastructure.
Much of the country’s internet traffic is routed through the state-controlled Telecommunications Infrastructure Company and the National Information Network—a centralized system designed to monitor and control the flow of data in and out of the country. This setup allows Iranian authorities to quickly block online services or enforce widespread shutdowns when unrest intensifies.
Experts warn that internet shutdowns carry severe consequences. Modern societies depend on digital connectivity for communication, commerce, healthcare, and public safety. Even short-term disruptions can cripple essential services, while prolonged blackouts can cause lasting economic and social damage.
Iran’s blackout is part of a broader global trend. Since January 2024, governments worldwide have imposed at least 97 intentional internet shutdowns, according to the Internet Society.
