Technical Details
The primary technical indicator of the disruption was a sharp drop in active network reachability. The ping-slash24 signal, which measures ICMP reachability across IPv4 network blocks, recorded a severity score of 2,644. This metric showed a 74% drop from its peak value during the observation period.
Other measurement signals showed varying impacts. The gtr-norm signal, which tracks deviations from expected traffic volume, fell by 89%. The merit-nt signal, a proxy for aggregate connectivity, dropped by 61%. The Border Gateway Protocol (BGP) control plane, responsible for routing announcements between networks, remained stable throughout the event, showing no significant change.
The disruption remained ongoing at last observation.
