Laos Experiences Brief BGP Disruption, Connectivity Stable

Laos experienced a brief disruption to its Border Gateway Protocol (BGP) control plane on Thursday, July 31, 2026. The event lasted approximately one hour, beginning at 04:20 UTC and concluding by 05:25 UTC. The disruption was isolated to the BGP signal, with other connectivity metrics remaining largely stable.

Technical Details

The BGP signal, which measures the routing control plane visibility for internet prefixes, recorded a severity score of 70 during the event. The signal’s median value dropped by 1% from its peak. In contrast, active probing for IPv4 reachability and traffic volume signals showed no significant correlated degradation during the observation window from 02:30 to 08:30 UTC. The ping-slash24 signal, measuring ICMP reachability across IPv4 /24 prefixes, recorded only a 7% drop from its peak. The gtr-norm signal, a forecast deviation from expected traffic baseline, and the merit-nt signal, a backscatter-based connectivity proxy, showed larger percentage drops but were not flagged as part of the primary disruption event.

The cause has not been publicly attributed.

Connectivity was reported restored by 05:25 UTC.
