Angola’s internet control plane experienced a brief but significant disruption early on August 29, 2026. The event, which lasted approximately 55 minutes, was characterized by a sharp degradation in BGP visibility, a key signal for network routing stability.
Technical Details
The disruption began at 03:35 UTC and concluded by 04:30 UTC. The primary affected signal was the BGP median, which recorded a severity score of 83. The BGP signal measures the control plane visibility for network prefixes, indicating a reduction in the number of globally visible routing paths.
Concurrent measurements showed correlated impacts on other connectivity metrics. The gtr-norm signal, which measures deviation from an expected traffic baseline, fell by 57% from its peak. The merit-nt signal, an aggregate connectivity proxy based on backscatter measurements, dropped by 66%. The ping-slash24 signal, measuring ICMP reachability across IPv4 /24 prefixes, showed a 7% reduction in reachable networks.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation window.
