In late December 2025, protests erupted in Iran, initially sparked by inflation and food prices but quickly escalating into demands for regime change. As tensions rose, the Iranian government responded with an extensive internet shutdown. By January 8, 2026, internet traffic from Iran plummeted by 90%, with IPv6 traffic dropping from over 48 million addresses to just 737,000. This dramatic decline indicated a deliberate disruption of connectivity, cutting Iran off from the global internet. Following the shutdown, there were brief moments of restored connectivity on January 9. Access to Cloudflare's public DNS resolver spiked briefly, and some universities regained access for a short time. However, this was short-lived, with traffic from these networks disappearing again by mid-afternoon. Prior to the shutdown, noticeable shifts in HTTP traffic were observed, particularly a decline in HTTP/3 usage on major networks like IranCell and TCI, indicating increased filtering and censorship. As of January 10, 2026, Iran remains largely disconnected from the internet, with traffic volumes hovering at less than 0.01% of pre-shutdown levels. Cloudflare continues to track these developments, providing real-time data on the state of internet connectivity in the country. The situation reflects the Iranian government's ongoing strategy to control information flow during times of civil unrest.
