Guinea Experiences Major Internet Disruption Lasting Nearly Three Hours

Guinea experienced a significant internet connectivity disruption on August 7, 2026, lasting nearly three hours. The event began around 16:10 UTC and concluded by 19:00 UTC, with a high overall severity score of 19.6 billion. Multiple network measurement signals recorded substantial degradation during the period.

Technical Details

The disruption was characterized by a sharp drop in several key connectivity metrics. The ping-slash24 signal, which measures ICMP reachability across IPv4 network prefixes, recorded a severity score of 5,053 and saw a 45% drop from its peak. The Border Gateway Protocol (BGP) control plane signal, which indicates the visibility of network prefixes to the global internet, recorded a severity score of 556 and an 11% drop. The gtr-norm signal, a forecast deviation from expected traffic baseline, fell by 79% from its peak with a severity score of 6,985. The merit-nt backscatter measurement, an aggregate connectivity proxy, fell to zero during the event.

The cause has not been publicly attributed.

Connectivity was reported restored by the end of the observation window.
