South Sudan Experiences BGP Control Plane Disruption

South Sudan experienced a disruption to its internet control plane on Saturday, July 12, 2026. The event began at approximately 12:55 UTC and lasted for nearly four hours, with connectivity stabilizing by 16:30 UTC. The disruption primarily impacted the Border Gateway Protocol (BGP), which manages routing information between networks.

Technical Details

The event recorded a severity score of 378, centered on the BGP signal. The bgp.median signal, which measures the visibility of network prefixes in the global routing table, showed a drop of approximately 2% from its peak value during the observation window. Concurrent measurements of IPv4 reachability, known as ping-slash24, showed a more pronounced drop of 11% from its peak, indicating reduced data plane connectivity that coincided with the control plane issue.

Reported Cause

The cause of the disruption has not been publicly attributed.

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