Cote D’Ivoire Connectivity Disruption Lasted Over Three Hours
Cote D’Ivoire experienced a significant connectivity disruption in the early hours of June 24, lasting over three hours. The event, which began at 01:20 UTC and concluded by 04:30 UTC, was characterized by a sharp reduction in network reachability. The primary technical impact was observed in active probing measurements across the country’s IPv4 address space.
Technical Details
The disruption recorded a severity score of 3,878, with the core impact centered on the ping-slash24 signal. This signal measures ICMP reachability across IPv4 /24 network prefixes, indicating a drop in successful responses from active probes. The signal’s median value dropped by 17% from its peak during the event.
Other measurement signals showed varied impacts. The gtr.sarima signal, which forecasts deviations from expected traffic baselines, recorded a 71% drop from its peak. The merit-nt signal, a proxy for aggregate connectivity based on backscatter measurements, also showed a 71% decline. The Border Gateway Protocol (BGP) control plane signal, which tracks routing advertisement visibility, remained stable throughout the period, showing no significant change.
The cause has not been publicly attributed. The disruption was reported as resolved by 04:30 UTC.
