Burkina Faso experienced a significant connectivity degradation beginning May 18 and lasting over six days. The disruption, which concluded around 00:30 UTC on May 25, primarily affected network reachability across the country’s IPv4 address space. The event registered a severity score of 234,686.
Technical Details
The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes. Its severity score for the event was 234,686, with a recorded drop in activity of 11% from its peak. The disruption period lasted approximately 6.4 days.
Other network signals showed varying impacts. The gtr.sarima signal, which forecasts deviations from expected traffic baselines, recorded a 27% drop from its peak. The merit-nt signal, a backscatter measurement that serves as an aggregate connectivity proxy, showed a 71% decline. The Border Gateway Protocol (BGP) control plane signal, indicating prefix visibility, remained largely stable with a negligible 0% drop.
Reported Cause
The cause of the prolonged degradation has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
