Côte d’Ivoire Connectivity Degradation Lasted Nearly 10 Hours
Côte d’Ivoire experienced a significant degradation in internet connectivity beginning on June 13, lasting nearly 10 hours. The disruption, which started around 14:40 UTC, was characterized by a sharp drop in network reachability. The cause has not been publicly attributed.
Technical Details
The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across the country’s core IPv4 address blocks. This signal recorded a severity score of 10,023 over the event’s duration. The degradation occurred in two distinct periods: a 6-hour period from 14:40 to 20:50 UTC with a severity of 7,402, followed by a shorter period from 22:20 UTC on June 13 until 00:30 UTC on June 14 with a severity of 2,621.
Other network signals showed varying impacts. The gtr.sarima signal, which forecasts deviations from expected traffic baselines, recorded a 66% drop from its peak. The merit-nt signal, a proxy for aggregate connectivity, also fell by 56%. The bgp control plane signal, which measures routing advertisement visibility, remained stable throughout the event.
The disruption remained ongoing at last observation.
