Côte d’Ivoire Connectivity Degradation Lasted Seven Days

Côte d’Ivoire experienced a significant, week-long degradation in internet connectivity beginning on August 4. The disruption, which lasted until August 11, was characterized by a severe drop in network reachability and control plane stability.

Technical Details

The event recorded an aggregate severity score of 67,117,664,357. The primary affected signals were ping-slash24, which measures ICMP reachability across IPv4 network blocks, and BGP, which reflects the stability of routing announcements. The ping-slash24 signal recorded a severity score of 421,984, while the BGP signal recorded a score of 159,053.

Supplementary measurements showed a 29% drop from peak in the gtr traffic signal and a 65% deviation from the expected traffic baseline indicated by the gtr-sarima forecast. Backscatter measurements from the ucsd-nt signal, a proxy for aggregate connectivity, fell by 32% from their peak.

Reported Cause

The cause of the prolonged disruption has not been publicly attributed.

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