Mali Experiences Two-Week BGP Disruption

Mali experienced a significant, prolonged disruption to its Border Gateway Protocol (BGP) routing from July 30 to August 13, 2026. The event lasted for 14 days and registered a severity score of 22,974. The disruption was isolated to the BGP control plane, which governs the visibility of network prefixes across the global internet.

Technical Details

The primary affected metric was the BGP median signal, which recorded a consistent drop in visible prefixes. The severity score of 22,974 reflects the scale and duration of this control plane event. Other internet measurement signals showed less severe concurrent impacts. The ping-slash24 signal, which measures ICMP reachability across IPv4 network blocks, recorded only a minor 4% drop in reachability. The gtr-norm signal, a forecast deviation from expected traffic baselines, showed a 36% drop from its peak, while the merit-nt signal, a backscatter-based aggregate connectivity proxy, fell by 41%.

The cause has not been publicly attributed.

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