Tajikistan Experiences Brief BGP Control Plane Disruption

Tajikistan experienced a brief disruption to its internet control plane on Monday, July 21, 2026. The event was recorded between 12:45 and 13:05 UTC, lasting approximately 20 minutes. The primary impact was observed on the Border Gateway Protocol (BGP), which governs how networks announce and route traffic.

Technical Details

The disruption registered a severity score of 22, with the BGP signal being the only one formally affected. The BGP signal measures the stability of routing announcements between networks; a drop indicates a reduction in the visibility of Tajikistan’s network prefixes to the global internet. During the event, the median number of visible prefixes dropped by 2% from its peak. Other connectivity metrics, including active probing reachability and traffic volume, showed minor fluctuations but did not cross disruption thresholds.

The cause has not been publicly attributed.

Network conditions were reported as stable following the brief event.
