The Solomon Islands experienced a week-long disruption to its internet routing infrastructure, beginning on July 31 and concluding on August 7. The event primarily affected the Border Gateway Protocol (BGP) control plane, which governs how network traffic is directed across the global internet. No significant degradation in active data-plane connectivity was reported during the period.

Technical Details

The disruption to the BGP signal, which measures the visibility of network prefixes in the global routing table, recorded a severity score of 29,318. The event lasted for a full seven days, from 00:45 UTC on July 31 to 00:30 UTC on August 7. Concurrent measurements of active ICMP reachability across IPv4 address blocks showed only a minor, 14% reduction from peak levels, indicating that end-user connectivity was largely maintained despite the routing anomaly. Backscatter measurements, a proxy for overall network activity, showed a complete drop to zero during the observation period.

Reported Cause

The cause of the prolonged BGP disruption has not been publicly attributed by network operators or government authorities in the Solomon Islands.

Routing visibility was restored by the end of the observation window.
