Solomon Islands Connectivity Disruption Affects BGP Control Plane

Solomon Islands experienced a disruption to its internet connectivity on Wednesday, July 30, 2026. The event primarily affected the Border Gateway Protocol (BGP) control plane, which manages routing between networks. The disruption lasted approximately one hour and ten minutes, beginning at 04:05 UTC and concluding by 05:15 UTC.

Technical Details

The event recorded a severity score of 272. The BGP signal, which measures the visibility of network prefixes in the global routing table, showed a 4% drop in its median value during the disruption. This indicates a reduction in the number of network routes being advertised from within the country. Concurrently, active probing for ICMP reachability across IPv4 /24 prefixes showed a 16% drop in the number of responsive networks. A separate backscatter measurement signal, which serves as a proxy for aggregate connectivity, dropped to zero during the event.

The cause has not been publicly attributed.

Connectivity was reported restored by the end of the observation period.
