Internet connectivity at the time
Internet connectivity in Hong Kong dropped 17 hours after this event, and stayed disrupted for about 11 minutes.
From 07 Sep 2026 23:04 UTC to 07 Sep 2026 23:15 UTC. Detected by background internet traffic — networks that went quiet.
Internet outages have many causes — damaged cables, power failures, network maintenance and deliberate shutdowns among them. IODA detects the loss of connectivity and does not attribute it to anything. This is shown because it happened at the same time, not because one caused the other.
Measured by IODA, Georgia Institute of Technology.
