Technical Details
The event recorded a severity score of 2,144. The ping-slash24 signal, which measures ICMP reachability across IPv4 network blocks, showed a 32% drop from its peak value. The gtr-norm signal, a proxy for traffic volume, also registered a 22% decline from its peak. The merit-nt backscatter measurement indicated a 14% drop in aggregate connectivity. Border Gateway Protocol (BGP) control plane visibility remained stable throughout the event, showing no significant change.
The cause has not been publicly attributed. Connectivity was reported restored by the end of the observation period.
