Burundi Connectivity Disruption Linked to BGP Signal Degradation

Burundi experienced a connectivity disruption early Thursday, primarily affecting the network control plane. The event began at 00:20 UTC and lasted for approximately four hours, concluding by 04:30 UTC. The degradation was most pronounced in the Border Gateway Protocol (BGP) signal, which registered a severity score of 654.

Technical Details

The disruption’s primary technical indicator was a degradation in the BGP signal, which measures the stability of routing announcements and control plane visibility for internet prefixes. The signal’s median value dropped by approximately 3% from its peak during the event. Concurrently, a separate backscatter measurement signal, which serves as a proxy for aggregate network activity, fell to zero, indicating a complete loss of observable traffic from that vantage point. Active probing for IPv4 reachability also showed a reduction, with a measured drop of 10% from its peak levels during the observation window.

The cause has not been publicly attributed.

Connectivity was reported restored by the end of the observation period.
