Guinea experiences brief internet connectivity disruption
Guinea experienced a brief but significant internet connectivity disruption on Wednesday, June 4. The event, which lasted approximately 40 minutes, was characterized by a sharp drop in network reachability across the country’s IPv4 address space.
Technical Details
The disruption began at 11:50 UTC and concluded by 12:30 UTC. The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes. This signal recorded a severity score of 1,908, indicating a substantial impact on basic connectivity.
During the event, the reachability metric dropped by 56% from its observed peak. Other network signals showed concurrent deviations. The Border Gateway Protocol (BGP) control plane signal, which reflects routing visibility for Guinea’s IP prefixes, showed a 4% decline. The gtr-norm signal, a forecast model for expected traffic, deviated from its baseline by 49%.
Reported Cause
The cause of the disruption has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
