Cote D’Ivoire Connectivity Degradation Lasted One Hour
Cote D’Ivoire experienced a one-hour degradation in internet connectivity late Friday. The disruption began at 23:30 UTC on June 12 and concluded by 00:30 UTC on June 13. The event was characterized by a significant drop in network reachability measurements.
Technical Details
The primary affected signal was ping-slash24, which measures ICMP reachability across the country’s IPv4 /24 address prefixes. This signal recorded a severity score of 1,256 during the event, indicating a notable reduction in active network probes receiving responses.
Other measurement signals showed concurrent deviations. The gtr.sarima signal, which forecasts deviations from expected traffic baselines, recorded a 33% drop from its peak. The merit-nt signal, a proxy for aggregate connectivity based on backscatter measurements, showed a more pronounced 71% drop from its peak. The BGP control plane signal, which monitors routing advertisement visibility, remained stable throughout the period.
The cause has not been publicly attributed.
Connectivity was reported restored following the one-hour disruption window.
