Guinea Experiences Brief BGP Control Plane Disruption

Guinea’s internet connectivity experienced a brief disruption on Wednesday, August 5, 2026, centered on the network control plane. The event lasted for approximately 55 minutes, starting at 14:35 UTC and concluding by 15:30 UTC.

Technical Details

The disruption registered a severity score of 219. The primary affected signal was the Border Gateway Protocol (BGP) median, which measures the control plane visibility of network prefixes. The signal recorded a drop of 4% from its peak value during the event.

Other measurement signals showed minor deviations. The ping-slash24 signal, which measures ICMP reachability across IPv4 /24 prefixes, showed a 10% drop. The gtr-norm signal, a forecast deviation from expected traffic baselines, recorded a 73% drop from its peak. The merit-nt signal, a backscatter measurement that serves as a proxy for aggregate connectivity, fell to zero during the event’s peak.

The cause has not been publicly attributed.

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