Laos experienced a brief disruption to its internet routing control plane in the early hours of July 18, 2026. The event, which lasted approximately one hour, was characterized by a degradation in the BGP signal, a key metric for network prefix visibility. The disruption began at 03:25 UTC and concluded by 04:30 UTC.
Technical Details
The event recorded a severity score of 71, focused on the BGP (Border Gateway Protocol) signal. This signal measures the stability and visibility of network routing announcements in the global control plane. During the disruption, the median BGP visibility count dropped by 1% from its peak. Concurrent measurements of active IPv4 prefix reachability showed an 8% drop, while a separate backscatter measurement proxy for aggregate connectivity recorded a complete, temporary cessation of traffic.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
