Nigeria Experiences Multi-Day BGP Connectivity Disruption

Nigeria experienced a prolonged connectivity disruption affecting its internet control plane from August 9 to August 12. The event, which lasted approximately 2.3 days, was characterized by a significant degradation in Border Gateway Protocol (BGP) visibility, a key signal for routing stability.

Technical Details

The disruption began on August 9 at 17:15 UTC and concluded on August 12 at 00:30 UTC. The primary affected signal was BGP, which registered a severity score of 3,431. The BGP signal measures the control plane visibility of internet routing prefixes. Concurrently, a secondary backscatter measurement signal, which serves as a proxy for aggregate connectivity, recorded a drop of 44% from its peak value during the observation period. Other network health indicators, including active probing for IPv4 reachability and traffic volume forecasts, showed more modest deviations.

The cause has not been publicly attributed.

Network conditions were reported as restored by the end of the observation window.
