Burkina Faso experiences prolonged connectivity degradation
Burkina Faso experienced a significant, prolonged degradation in internet connectivity beginning on May 18. The disruption lasted for over 11 days, with a severe impact on network reachability before restoration was observed on May 30.
Technical Details
The primary disruption was measured by a severe drop in the ping-slash24 signal, which recorded a severity score of 417,549. This signal measures ICMP reachability across IPv4 /24 network prefixes, indicating a substantial reduction in active, responsive internet infrastructure.
Other measurement signals showed varied impacts. The gtr.sarima signal, which forecasts deviation from expected traffic baselines, recorded a 27% drop from its peak. The merit-nt signal, a proxy for aggregate connectivity based on backscatter measurements, showed an 85% decline from its peak. The border gateway protocol (BGP) signal, reflecting control plane visibility for network prefixes, remained largely stable throughout the event.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
