Côte d’Ivoire Experiences Connectivity Degradation
Côte d’Ivoire experienced a significant connectivity disruption on June 21, 2026, with degraded network reachability observed for nearly six hours. The event began at 18:50 UTC and persisted until 00:30 UTC the following day, registering a severity score of 3,850. The primary impact was measured in the active probing of IPv4 network prefixes.
Technical Details
The disruption was most pronounced in the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes. This signal recorded a severity score of 3,850, with two distinct periods of degradation. The first occurred between 18:50 and 19:50 UTC, scoring 1,204. A second, more severe period followed from 22:20 UTC on June 21 to 00:30 UTC on June 22, scoring 2,646.
Other network health indicators showed varied impacts. The gtr.sarima signal, which forecasts deviation from an expected traffic baseline, recorded a 28% drop from its peak. The normalized version of this signal, gtr-norm, showed a 67% drop. The merit-nt signal, a backscatter measurement used as a proxy for aggregate connectivity, registered a 70% drop from its peak. The border gateway protocol (BGP) control plane signal, which reflects routing visibility for network prefixes, showed no measurable change during the event.
Reported Cause
The cause of the disruption has not been publicly attributed.
Network reachability was reported restored by 00:30 UTC on June 22.
