Afghanistan experiences BGP control plane disruption

Afghanistan experienced a Border Gateway Protocol (BGP) control plane disruption on Friday, July 25, 2026. The event lasted approximately 50 minutes, beginning at 11:40 UTC and concluding by 12:30 UTC. The primary impact was observed in the BGP signal, which measures the visibility of network prefixes to the global internet routing table.

Technical Details

The disruption recorded a severity score of 133. The BGP signal, which tracks the number of visible network prefixes, showed a measurable decline during the event. The median number of visible prefixes dropped by 3% from its peak, averaging 642 visible prefixes across the observation window. Other internet measurement signals, including active probing for reachability and traffic volume indicators, showed minimal deviation from baseline levels during the same period.

The cause has not been publicly attributed.

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