FLAG Atlantic-1 (FA-1)

FLAG Atlantic-1 (FA-1) is a cross-regional submarine cable connecting United States, France, United Kingdom. Its 4 landing points at Island Park, Northport, Plerin, Skewjack bridge the networks of North America, Europe, providing an important path for international data traffic. The transatlantic corridor has been connected by submarine cables since 1858, when the first telegraph cable was laid between Ireland and Newfoundland. GeoCables tracks this cable using RIPE Atlas measurements from four probes in Minsk, Almaty, Tbilisi, and Jerusalem, comparing live RTT against historical baselines to catch performance shifts early.
