EXA Express

EXA Express is a cross-regional submarine cable connecting United Kingdom, Ireland, Canada. Its 3 landing points at Brean, Cork, Halifax bridge the networks of Europe, North America, 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.
