Antarctica experienced a sustained disruption to its internet control plane visibility lasting more than two days. The event began on August 29 and concluded on September 1, affecting the Border Gateway Protocol (BGP) signal used to track network routing announcements.
Technical Details
The disruption was observed from August 29 at 15:25 UTC until September 1 at 00:30 UTC, a duration of approximately 2.4 days. The event registered a severity score of 30,222, based on the degradation of the BGP signal. This signal measures the visibility of network routing prefixes in the global control plane, indicating potential issues with how networks in the region were being advertised to the wider internet. Other connectivity signals, including active probing for IPv4 reachability, showed minimal deviation during the same period.
Reported Cause
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
