French Guiana Internet Control Plane Disrupted for 50 Minutes

French Guiana experienced a brief but significant disruption to its internet control plane on Thursday, August 6, 2026. The event, which lasted approximately 50 minutes, was characterized by a sharp reduction in Border Gateway Protocol (BGP) route visibility. The disruption began at 17:05 UTC and concluded by 17:55 UTC.

Technical Details

The disruption registered a severity score of 150. The primary affected signal was the BGP median, which measures the control plane visibility of internet routing prefixes. This metric recorded a drop of 3% from its peak during the observation window.

Other network telemetry showed concurrent but less severe anomalies. Active probing for ICMP reachability across IPv4 /24 prefixes showed a 16% drop from its peak. A separate backscatter measurement, which serves as a proxy for aggregate connectivity, recorded a more substantial 67% decline from its observed maximum.

The cause has not been publicly attributed. No official statements or news reports regarding the cause of the disruption were identified in the immediate aftermath.

Network conditions were reported as restored by the end of the observation period.
