Burkina Faso experienced a significant connectivity disruption lasting more than five days, beginning on May 18. The event was characterized by a severe degradation in network reachability, with a peak severity score of 198,115 recorded against the ping-slash24 signal.
Technical Details
The disruption lasted from approximately 14:30 UTC on May 18 until 00:30 UTC on May 24. The primary affected signal was ping-slash24, which measures ICMP reachability across IPv4 /24 prefixes. This signal recorded a severity score of 198,115, indicating a substantial drop in network responsiveness.
Other monitored signals showed varying impacts. The bgp signal, which reflects control plane visibility for network prefixes, remained largely stable. The gtr.sarima signal, a forecast deviation from expected traffic baselines, and the ucsd-nt signal, a proxy for aggregate connectivity via backscatter measurements, both recorded data points but did not show the same level of acute severity as the ping-slash24 metric.
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.
