Burundi Internet Connectivity Disrupted for Over Two Hours

Burundi experienced a significant internet connectivity disruption on Sunday, July 13, lasting over two hours. The event began at approximately 18:00 UTC and concluded around 20:20 UTC. The primary impact was observed in the reachability of the country’s core internet infrastructure.

Technical Details

The disruption was characterized by a sharp decline in the ping-slash24 signal, which measures ICMP reachability across active IPv4 /24 network prefixes. The signal recorded a severity score of 3,085, with a 41% drop from its peak value during the observation window. This indicates a substantial reduction in the ability to contact a wide range of network addresses within the country.

Other measurement signals showed varied impacts. The gtr-norm signal, which tracks deviation from an expected traffic baseline, fell by 12%. The merit-nt signal, a proxy for aggregate connectivity derived from backscatter measurements, dropped to zero. The Border Gateway Protocol (BGP) control plane signal, reflecting routing table visibility, remained stable throughout the event.

Reported Cause

The cause of the disruption has not been publicly attributed.

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