Guinea-Bissau experienced a brief but notable disruption to its internet routing infrastructure on Wednesday, July 9, 2026. The event, which primarily affected the Border Gateway Protocol (BGP), lasted for approximately one hour and twenty-five minutes, starting around 15:05 UTC and concluding by 16:30 UTC.
Technical Details

The BGP signal, which measures the visibility of network prefixes to the global routing system, showed a 3% drop from its peak during the observation window. Concurrently, a secondary measurement of active ICMP reachability across IPv4 address blocks also recorded an 11% decline from its peak, though this signal was not flagged as the primary disruption.
