Doug MadoryIran is in the 10th day of the second internet shutdown of 2026.
Within the small amount of traffic that continues to trickle out of Iran since Feb-28, several networks experienced further drops in traffic volume on Mar-5 possibly due to airstrikes.
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.

Routes have been down since the beginning of the latest shutdown on Feb-28, but came back on Mar-8.
