Cote d’Ivoire Experienced Brief Connectivity Degradation
Cote d’Ivoire experienced a brief, localized connectivity disruption in the early hours of May 31, 2026. The event lasted approximately one and a half hours, starting at 03:00 UTC and concluding by 04:30 UTC. The primary technical impact was observed in active network reachability measurements.
Technical Details
The disruption registered a severity score of 1,923 based on degraded ping-slash24 signals. This signal measures ICMP reachability across IPv4 network prefixes, indicating a reduction in successful active probes during the event window.
Other network signals showed varied impacts. The gtr.sarima signal, which forecasts deviations from expected traffic baselines, recorded a 72% drop from its peak. The normalized version of this signal showed an 83% drop. The ucsd-nt signal, a backscatter measurement used as a proxy for aggregate connectivity, fell by 54% from its peak. Border Gateway Protocol (BGP) control-plane visibility remained stable throughout the period, showing no observable drop.
The cause has not been publicly attributed. The disruption was resolved by the end of the observation window.
