Rwanda experienced a short-lived connectivity disruption late on July 9, affecting the country’s internet control plane visibility. The event lasted approximately 50 minutes, beginning around 23:55 UTC and concluding by 00:45 UTC on July 10.

Technical Details

The disruption registered a severity score of 1,103, primarily impacting the Border Gateway Protocol (BGP) signal. BGP is the system that manages how data packets are routed across the internet between different networks. The median BGP visibility for Rwandan networks dropped by 22% from its peak during the event.

Other network signals showed concurrent anomalies. The ping-slash24 signal, which measures ICMP reachability across IPv4 network blocks, also recorded a 22% drop in reachable networks. The gtr-norm signal, a traffic volume baseline, fell by 65% from its peak. The merit-nt signal, a proxy for aggregate connectivity, dropped to zero during the event’s peak. The cause has not been publicly attributed.

Network conditions were reported as restored following the event.
