Nearly all of the Iranian internet has been down for 43+ hours but, as was the case with last month's shutdown, there is a tiny amount of traffic still getting passed. Within the remaining traffic, we can see subsequent outages, possibly caused by continued US/IL airstrikes…🧵

Internet connectivity in Iran is now in a near-complete shutdown, down about 98% vs the previous week. The disruption began around 07:00 UTC, following reports of military strikes — and in past incidents the government has responded with nationwide Internet shutdowns.

IODA shows the Internet in Iran has been cutoff from the global Internet since ~7:00 AM UTC. The regime implemented a similar Internet shutdown when Israel attacked Iran in June of 2025. Follow connectivity in Iran in near realtime: ioda.inetintel.cc.gatech.edu/country/IR?f...

Internet connectivity down in Iran as airstrikes hit the country. Traffic volume dropped at 07:06 UTC and then again at 11:47 UTC with minimal connectivity remaining. The country had a partial restoration since Jan-27 following a complete shutdown in Jan-8.

Iran's shutdown is now 15 days and counting. Small amounts of service have been restored in recent days. #DigitalBlackoutIran #IranRevoIution2026 State telecom TIC (A49666) re-established many of its lost connections with outside providers, such as GBI (AS200612) at 22:02 UTC on Jan-22.

As two full weeks of #IranDigitalBlackout approaches, traffic again began to grow, starting around 18:00 UTC on 21-Jan. The growth was driven by large increases across several ASNs, and could potentially be related to an expanding whitelist of domains. radar.cloudflare.com/dns/ir?dateR...
