The current, ongoing near total Internet shutdown in Iran, disconnecting Iranians from the global Internet, is now longer than the January 2026 shutdown during nation-wide protests. This makes the current shutdown the longest shutdown IODA has documented in Iran.

Evidence of power shortage in Cuba is visible in IODA's Internet connectivity signals. The ~20% drop in Active Probing occurred earlier this month and appears similar to historic power outages visible in IODA data.

Iran's connectivity to the global Internet briefly recovered on March 12 6:35 PM - 6:55 PM local time when a state-owned network (AS58224) that 32.9% of the population in Iran is connected to appeared to toggle its routing announcements off-on-off-on over a 40-minute period.

During the short recovery, use of Mozilla's Firefox increased sharply.

Iran is down, but IPv4 BGP routes are still 98% up (@IODA). It is necessary the routes be up to selectively authorize internet access (i.e. whitelisting).

Conversely, when we see routes go down, we may infer that those events are not govt-directed.
