A prolonged connectivity disruption affected the British Virgin Islands from July 31 to August 14, with a primary impact on the network control plane. The event, which lasted approximately 13.6 days, was most severe on July 31 and concluded by 00:30 UTC on August 14.
Technical Details
The disruption registered a severity score of 39,010, primarily driven by anomalies in the Border Gateway Protocol (BGP) signal. BGP provides control plane visibility for network prefixes. The BGP signal remained at a constant, reduced level of 148 visible prefixes throughout the event.
Other network health indicators showed varied impacts. The gtr-norm signal, which measures deviation from an expected traffic baseline, recorded a maximum drop of 36% from its peak. The merit-nt signal, a proxy for aggregate connectivity based on backscatter measurements, dropped to zero at its lowest point. The ping-slash24 signal, which measures ICMP reachability across IPv4 /24 prefixes, showed an 8% reduction in reachable networks.
The cause has not been publicly attributed.
The disruption was resolved by the end of the observation period.
