In addition to the ongoing shutdown of the Internet in Iran, IODA sees evidence of damage to critical Internet or power infrastructure through simultaneous drops in Routing Announcements across various networks.

For example, at ~6:00 PM local time today we see 5 networks show simultaneous drops.

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.

As of 3:30 AM IST, January 27, IODA observed a sharp increase in Active Probing. This signal measures connectivity to the global Internet by pinging devices on Iranian networks and collecting responses in order to label networks as connected.

Signs of restoration of the Internet in Iran have not translated to meaningful connectivity with the global Internet for Iranians.

Signs of domestic Internet whitelisting are apparent as Google Search usage in-country ticks up.

IODA data confirms the ongoing, complete government-directed shutdown of the Internet in Iran since January 8th. Similar to the June 2025 shutdown during the Israel-Iran war, routing (BGP) is largely unaffected.

Specific networks, likely with permission from the Iranian government in a policy known as whitelisting, show signs of connectivity since 11:30 UTC / 3:00 PM local time. Many appear to be research or university networks.
