Antarctica experienced a disruption to its internet control plane visibility on August 29, lasting for over nine hours. The event primarily affected the Border Gateway Protocol (BGP) signal, which governs how network prefixes are announced and routed across the internet. The disruption was observed between 15:25 UTC on August 29 and 00:30 UTC on August 30.
Technical Details
The disruption recorded a severity score of 4,811. The affected BGP signal measures the stability and visibility of routing announcements for network prefixes. During the event, the signal showed no percentage drop from its peak but remained at a constant level of 31 measurement points. Other connectivity signals, including active probing for IPv4 reachability, showed minimal deviation.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
