Guam experienced a significant internet connectivity degradation lasting over nine days, from July 5 to July 15. The disruption, which primarily affected network reachability, recorded a severity score of 271,806. The event was observed from July 14 at 18:30 UTC through July 15 at 00:30 UTC.
Technical Details
The primary affected signal was ping-slash24, which measures ICMP reachability across IPv4 /24 network prefixes. The signal recorded a severity score of 271,806 over the 9.4-day event period. Other signals showed varying impacts: the gtr signal, a forecast deviation from expected traffic, dropped 73% from its peak. The gtr-norm signal, a normalized traffic measure, dropped 64%. The merit-nt signal, an aggregate connectivity proxy, dropped 85%. The BGP control plane signal, measuring routing visibility, remained stable with no observed drop.
Reported Cause
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation window.
