The U.S. Virgin Islands experienced a connectivity disruption affecting its internet control plane on August 21. The event began at 02:40 UTC and lasted approximately 1.8 hours, ending by 04:30 UTC. The primary impact was recorded on the Border Gateway Protocol (BGP) signal, which registered a severity score of 4,864.
Technical Details
The disruption was characterized by a significant drop in the BGP median signal, which measures the visibility of network prefixes in the global routing table. The signal fell 44% from its peak during the observation window. Other network health indicators showed less pronounced effects. The ping-slash24 signal, which measures ICMP reachability across IPv4 address blocks, saw a 5% drop. The merit-nt signal, a proxy for aggregate connectivity, recorded a 100% drop from its peak. The gtr-norm signal, which tracks deviations from expected traffic baselines, fell by 16%.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
