Nepal experienced a disruption to its internet routing control plane on Monday, September 1, 2026. The event, which lasted approximately three hours, was characterized by a significant degradation in the Border Gateway Protocol (BGP) signal.
Technical Details
The disruption began at 17:10 UTC and concluded by 20:30 UTC. The primary affected metric was the BGP median signal, which recorded a severity score of 504. This signal measures the visibility of network prefixes in the global routing table, indicating potential issues with route announcements and withdrawals. While the BGP signal showed a clear deviation, other key connectivity indicators, including active probing for IPv4 reachability and traffic volume forecasts, remained within normal operational ranges during the observation window.
The cause has not been publicly attributed.
Network routing was reported restored by the end of the observation period.
