Côte d’Ivoire Connectivity Degradation Observed Early June 21
Côte d’Ivoire experienced a connectivity disruption beginning at 00:30 UTC on June 21, lasting approximately four hours. The event was characterized by a significant drop in network reachability, with a severity score of 5,024 recorded for the affected signal.
Technical Details
The disruption was primarily observed through a degradation in the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 prefixes. The signal recorded a drop magnitude of -16% from its peak during the observation window from 22:30 UTC on June 20 to 04:30 UTC on June 21.
Other signals showed varying impacts. The gtr.sarima signal, which tracks deviation from an expected traffic baseline, recorded a -70% drop from its peak. The merit-nt signal, a proxy for aggregate connectivity, recorded a -80% drop. The Border Gateway Protocol (BGP) signal, reflecting control plane visibility for prefixes, showed no significant change.
Reported Cause
The cause of the disruption has not been publicly attributed.
Connectivity was reported restored by 04:30 UTC.
