Guam experienced a significant internet connectivity disruption that began on July 5 and persisted for more than six days. The degradation, which concluded on July 12, primarily affected the reachability of network prefixes across the island.
Technical Details
The disruption recorded a severity score of 184,894. The primary affected signal was ping-slash24, which measures ICMP reachability across IPv4 /24 prefixes. This signal showed a 12% drop from its peak reachability level during the event.
Other signals showed varied impacts. The gtr signal, a forecast deviation from expected traffic baselines, recorded a 63% drop from its peak. The merit-nt signal, a proxy for aggregate connectivity, fell to zero during the period. The Border Gateway Protocol (BGP) control plane, which manages routing visibility for prefixes, remained stable with no observable drop.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
