The British Virgin Islands experienced a significant connectivity disruption affecting its internet control plane, beginning on July 31 and lasting for approximately 1.6 days. The event was most pronounced in the Border Gateway Protocol (BGP) signal, recording a severity score of 4,680. Connectivity was observed returning to normal levels by 00:30 UTC on August 2.
Technical Details
The disruption’s primary technical signature was a sustained anomaly in the BGP signal, which measures the control plane visibility and routing stability of a country’s internet prefixes. The signal recorded a consistent value of 148 throughout the event window, indicating a persistent routing state. Other measurement signals showed varied impacts: active probing for IPv4 reachability saw an 8% drop from its peak, while a separate backscatter measurement signal recorded a complete 100% drop in observed traffic.
The cause has not been publicly attributed.
The disruption remained ongoing at last observation before restoration.
