Burkina Faso experienced a significant connectivity degradation lasting nearly four days, with a core internet reachability metric recording a severity score of 143,990. The disruption began on May 18 and concluded by the afternoon of May 22 UTC, affecting the country’s active network infrastructure.
Technical Details
The primary affected signal was ping-slash24, which measures ICMP reachability across active IPv4 network blocks. Its median value recorded the high severity score throughout the event. The gtr-norm signal, which tracks deviation from an expected traffic baseline, showed a 67% drop from its peak. The merit-nt signal, a proxy for aggregate connectivity, fell by 50%. The Border Gateway Protocol (BGP) control plane, which advertises network routes, remained largely stable, showing no significant drop.
Reported Cause
The cause of the multi-day disruption has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
