Nepal experienced a brief but notable disruption to its internet control plane on the morning of August 25, 2026. The event, which lasted just under an hour, was characterized by a significant drop in Border Gateway Protocol (BGP) visibility.
Technical Details
The disruption began at 07:35 UTC and concluded by 08:30 UTC, lasting approximately 0.9 hours. The primary affected metric was the BGP median signal, which recorded a severity score of 364. This signal measures the control plane visibility of internet routing prefixes, indicating a period where routing announcements became less stable or less visible globally.
Concurrently, other network health indicators showed deviations. The ping-slash24 signal, which measures ICMP reachability across IPv4 network blocks, showed an 18% drop from its peak. The Merit Network Telescope (merit-nt) backscatter signal, an aggregate proxy for overall connectivity, recorded a 28% drop. The normalized Google Traffic Router (gtr-norm) signal, which compares observed traffic to an expected baseline, fell by 69% from its peak.
The cause has not been publicly attributed.
Network conditions were reported as restored by the end of the observation window.
