U.S. Virgin Islands Experiences Connectivity Disruption
The U.S. Virgin Islands experienced a significant degradation in internet connectivity early on May 31, 2026. The disruption, which lasted approximately three and a half hours, was characterized by a sharp decline in network reachability. The event recorded a severity score of 4,102.
Technical Details
The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes. The signal’s severity score of 4,102 was derived from two distinct periods of degradation. The first occurred between 00:50 and 01:40 UTC, scoring 1,054. A second, more severe period followed from 01:50 to 04:10 UTC, scoring 3,048.
Other signals showed varied impacts. The gtr.sarima signal, which forecasts deviation from an expected traffic baseline, recorded a 15% drop from its peak. Its normalized counterpart, gtr-norm, showed an 81% drop. The merit-nt signal, a backscatter measurement that serves as an aggregate connectivity proxy, dropped to zero, indicating a complete loss of observable traffic. The bgp signal, reflecting control plane visibility for network prefixes, remained stable and showed no drop.
The cause has not been publicly attributed. Connectivity was reported restored by 04:10 UTC.
