Burkina Faso connectivity disruption persisted for over 13 days
Burkina Faso experienced a significant, prolonged connectivity disruption lasting more than 13 days, with the most severe degradation recorded in late May. The event, which began on May 18 and concluded on June 1, primarily impacted the reachability of the country’s IPv4 address space.
Technical Details
The disruption recorded a severity score of 490,692. The primary affected signal was the ping-slash24 measurement, which tracks ICMP reachability across IPv4 /24 prefixes. This metric showed a 12% drop from its peak reachability during the event.
Other signals showed varying impacts. The gtr.sarima signal, which measures deviation from an expected traffic baseline, recorded a 35% drop from its peak. The merit-nt signal, a backscatter-based aggregate connectivity proxy, showed a complete 100% drop from its observed peak. The Border Gateway Protocol (BGP) control plane, which provides visibility for network prefixes, remained largely stable, showing no significant drop.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
