Iran Experienced BGP Disruption Lasting Over Two Hours

Iran experienced a Border Gateway Protocol (BGP) disruption on August 15, 2026, lasting for over two hours. The event began at 06:15 UTC and concluded by 08:30 UTC, registering a severity score of 208. The disruption primarily affected the BGP control plane, which governs the visibility of network prefixes on the global internet.

Technical Details

The disruption was isolated to the BGP signal, which recorded a median severity score of 208 during the event. The BGP signal measures the stability and visibility of routing announcements for the country’s IP address blocks. Other connectivity metrics, including active probing for IPv4 reachability and traffic volume forecasts, showed minimal deviation from normal baselines during the same observation window.

The cause has not been publicly attributed.

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