Bhutan experienced a significant connectivity disruption beginning on July 18, 2026, which lasted for more than five hours. The event, which started at 19:25 UTC, primarily affected the network’s control plane visibility and was observed until 00:30 UTC on July 19.
Technical Details
The disruption recorded a severity score of 440. The primary affected signal was the Border Gateway Protocol (BGP) median, which measures the control plane visibility of network prefixes. The BGP signal showed a drop in visibility of approximately 1% from its peak during the event.
Other network telemetry signals also registered deviations. Active probing for ICMP reachability across IPv4 /24 prefixes showed an 11% drop from its peak. A separate traffic volume forecast model indicated a deviation of 44% below its expected baseline. Backscatter measurements, an aggregate connectivity proxy, showed a complete 100% drop from their peak value during the observation window.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
