Angola experienced a brief, sharp degradation in internet connectivity on Monday morning, July 21, 2026. The disruption was observed between approximately 09:28 and 10:20 UTC, lasting just under one hour. The primary technical impact was measured in a significant drop in backscatter traffic, a key proxy for overall network activity.
Technical Details
The event registered a severity score of 5,068. The Merit Network Telescope (merit-nt) signal, which measures unsolicited backscatter traffic as an aggregate indicator of connectivity, recorded a drop of 98% from its peak during the observation window. This signal fell from an average of 131.87 to a minimum of 2.4. Other key internet health indicators, including Border Gateway Protocol (BGP) control-plane visibility and active ICMP reachability tests across IPv4 networks, showed minimal deviation, indicating the disruption was primarily at the data-forwarding level.
The cause has not been publicly attributed. The disruption was resolved within the hour, with connectivity returning to prior levels.
