Guinea experienced a significant disruption to its internet control plane beginning July 20, lasting for approximately 1.4 days. The event, which concluded by 00:30 UTC on July 22, was characterized by a severe degradation in the country’s Border Gateway Protocol (BGP) visibility.
Technical Details
The disruption recorded a severity score of 2,643, centered on the BGP control plane signal. The BGP signal measures the visibility of a country’s internet routing prefixes to the global network. The BGP prefix count remained stable at 149 throughout the event, indicating no wholesale withdrawal of routes, but the median signal showed a significant anomaly.
Other network signals showed more moderate deviations. The ping-slash24 signal, which measures ICMP reachability across IPv4 /24 prefixes, showed an average 8% drop from its peak. The gtr-norm signal, a normalized measure of traffic volume, recorded an 18% drop from its observed peak.
Reported Cause
The cause of the prolonged control plane disruption has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
