French Guiana connectivity disruption linked to BGP instability

French Guiana experienced a connectivity disruption on Thursday, July 17, 2026, with a primary impact on the internet’s control plane. The event lasted approximately two hours and fifteen minutes, beginning at 10:15 UTC and concluding by 12:30 UTC.

Technical Details

The disruption registered a severity score of 407. The primary affected signal was the Border Gateway Protocol (BGP), which governs how networks announce and exchange routing information. A drop in the BGP median signal indicated reduced visibility of French Guiana’s network prefixes to the global routing system. Other measurement signals, including active probing for network reachability and traffic volume forecasts, showed lesser deviations during the same observation window.

The cause has not been publicly attributed.

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