Bhutan Experiences Brief BGP Disruption, Connectivity Restored

Bhutan experienced a brief but notable disruption to its internet control plane on Friday, July 18, 2026. The event, centered on the Border Gateway Protocol (BGP), lasted for approximately one hour before connectivity was restored.

Technical Details

The disruption began at 19:25 UTC and concluded at 20:30 UTC. The primary affected signal was BGP, which registered a severity score of 94. BGP is the protocol that manages the routing of traffic between different networks on the internet, and disruptions can affect the visibility of a country’s IP address prefixes to the global internet. During the event, the median BGP visibility count dropped by approximately 1% from its peak. Other internet measurement signals, including active probing for network reachability, showed minor concurrent fluctuations.

The cause has not been publicly attributed.

Connectivity was reported restored by the end of the observation period.
