Côte d’Ivoire Connectivity Degradation Lasted Over 10 Hours

Côte d’Ivoire experienced a significant degradation in internet connectivity beginning on July 20, 2026, which lasted for more than ten hours. The disruption, which peaked in severity around 14:00 UTC, primarily impacted the reachability of the country’s IPv4 address space. Connectivity was reported restored by 00:30 UTC on July 21.

Technical Details

The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes. This signal recorded a total severity score of 9,014 across three distinct disruption periods. The most severe period occurred between 14:00 and 19:30 UTC, accounting for a score of 6,740.

Other network signals showed varied impacts. The gtr-norm signal, a normalized measure of traffic flow, dropped by 39% from its peak. The merit-nt signal, a proxy for aggregate connectivity based on backscatter measurements, recorded a 58% drop. The Border Gateway Protocol (BGP) control plane, which manages routing announcements, remained stable throughout the event, showing no significant drop in visible prefixes.

The cause has not been publicly attributed.

The disruption remained ongoing at last observation before restoration.
