Côte d’Ivoire experienced a significant degradation in internet connectivity beginning late on July 14. The disruption, which lasted for approximately 25 hours, was characterized by a sharp decline in network reachability across the country’s IPv4 address space. The event concluded around 00:30 UTC on July 16.
Technical Details
The disruption recorded a severity score of 31,454, based on active probing measurements. The primary affected signal was ping-slash24, which measures ICMP reachability across IPv4 /24 network prefixes. This signal showed a 14% drop from its peak reachability levels during the event. Other network telemetry, including backscatter measurements, also indicated a substantial 72% drop in aggregate connectivity levels. Border Gateway Protocol (BGP) control plane visibility remained stable throughout the period, showing no significant withdrawal of advertised network prefixes.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
