Sierra Leone experienced a notable degradation in internet connectivity on Saturday, August 1, 2026. The disruption lasted for approximately two and a half hours, primarily affecting the network’s control plane visibility. The cause has not been publicly attributed.
Technical Details
The disruption began at 12:45 UTC and concluded by 15:20 UTC. The event registered a severity score of 199, with the primary impact observed on the Border Gateway Protocol (BGP) signal. BGP, which governs the exchange of routing information between networks, recorded a median visibility drop of 1% from its peak during the event.
Other network health indicators showed concurrent anomalies. Active probing for ICMP reachability across IPv4 address blocks recorded an 18% drop from its peak. A separate traffic volume forecast model indicated a 35% deviation from its expected baseline. Backscatter measurements, a proxy for aggregate connectivity, fell to zero during the peak of the event.
The disruption remained ongoing at last observation.
