Guinea Experiences Connectivity Disruption Affecting Internet Reachability
Guinea experienced a significant internet connectivity disruption on Wednesday, May 28, 2026, with two distinct periods of degraded reachability. The disruption primarily affected the active probing of IPv4 network prefixes, with a total severity score of 3,103 recorded over an observation window from 06:30 to 12:30 UTC.
Technical Details
The primary degradation was observed in the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 prefixes. The signal recorded a severity score of 3,103, with two distinct outage periods. The first lasted from 09:10 to 10:30 UTC with a score of 2,207, and the second occurred from 11:40 to 12:20 UTC with a score of 897. The total duration of the disruption was approximately 3.2 hours.
Other signals showed varied performance. The Border Gateway Protocol (BGP) control plane, which governs routing visibility for network prefixes, remained stable with no observed drop. The gtr.sarima signal, which measures deviation from an expected traffic baseline, recorded a 61% drop from its peak. The merit-nt signal, a proxy for aggregate connectivity based on backscatter measurements, showed a 100% drop from its peak.
The cause has not been publicly attributed. Connectivity was reported restored by the end of the observation period.
