The Democratic Republic of the Congo experienced a connectivity disruption on August 23, centered on instability in the network control plane. The event lasted approximately three and a half hours, from 16:20 to 19:50 UTC, with a severity score of 227.
Technical Details
The primary affected signal was the Border Gateway Protocol (BGP), which recorded a median visibility drop. BGP is the control plane protocol that manages the global routing table, and disruptions can affect the visibility of network prefixes. The event coincided with measurable drops in other connectivity proxies. The gtr-norm signal, which measures deviation from expected traffic volume, fell 30% from its peak. The merit-nt backscatter measurement, an aggregate connectivity proxy, recorded a 63% drop from its peak. Active probing for ICMP reachability across IPv4 /24 prefixes showed a 7% decline.
The cause has not been publicly attributed.
Network conditions were reported restored by the end of the observation period.
