Antarctica experienced a significant disruption to its internet control plane visibility over a 1.4-day period ending early Monday. The event, affecting the Border Gateway Protocol (BGP) signal, began on August 29 and concluded by 00:30 UTC on August 31.
Technical Details
The disruption recorded a severity score of 17,516, with the primary impact on the BGP signal. The BGP signal measures the control plane visibility for internet routing prefixes. Concurrent measurements of the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 prefixes, showed a less severe 6% drop from its peak during the observation window.
Reported Cause
The cause of the disruption has not been publicly attributed.
