The U.S. Virgin Islands experienced a significant connectivity disruption on August 21, 2026, primarily affecting the network’s control plane. The event lasted nearly 20 hours, with a severity score of 52,745 recorded for the Border Gateway Protocol (BGP) signal.
Technical Details
The disruption began at 02:40 UTC and concluded at 22:35 UTC. The primary affected signal was BGP, which measures the control plane visibility and routing announcements for network prefixes. The BGP signal recorded a 44% drop from its peak value during the event. Other network health indicators also showed deviations. The ping-slash24 signal, which measures ICMP reachability across IPv4 network blocks, showed a 9% drop. The merit-nt signal, an aggregate connectivity proxy based on backscatter measurements, recorded an 83% drop from its peak.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
