South Sudan Experiences Border Gateway Protocol Disruption

South Sudan experienced a significant disruption to its Border Gateway Protocol (BGP) routing infrastructure, lasting approximately one and a half days. The event began on July 12 at 12:55 UTC and concluded on July 14 at 00:30 UTC, affecting the control plane visibility of the country’s internet prefixes.

Technical Details

The disruption registered a severity score of 3,746, based on the degradation of the BGP signal. The BGP signal measures the control plane visibility and stability of advertised internet routes. During the event, the number of visible BGP routes remained at a constant 112, showing no percentage drop from its peak, but the severity score indicates a significant routing anomaly. Other connectivity metrics, including active probing for reachability and traffic volume, showed minimal deviation from normal baselines.

The cause has not been publicly attributed.

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