Cote D’Ivoire experienced a significant, prolonged connectivity disruption that began on August 4 and remained ongoing through the morning of August 18. The event, spanning 14 days, affected both the internet’s control and data planes, leading to a severe degradation in network reachability and stability.
Technical Details
The disruption registered a high overall severity score of 269,535,947,096. The primary technical signals affected were the Border Gateway Protocol (BGP) and active probing of IPv4 address blocks. BGP, which manages the routing of traffic between networks, showed a sustained anomaly with a severity score of 318,736. Concurrently, active ICMP reachability testing across IPv4 /24 prefixes recorded a more pronounced impact with a severity score of 845,641, indicating widespread packet loss and unreachability for end-users.
Other network telemetry showed correlated deviations. Backscatter traffic measurements, a proxy for overall internet activity, fell by approximately 30% from their peak during the observation period. The cause of the prolonged disruption has not been publicly attributed.
The connectivity issues were still present at the last observation at 00:30 UTC on August 18.
