Its 5 landing points at Coleraine, Dublin, Halifax, Lynn, Southport 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 maintains health checks on this cable using distributed RIPE Atlas probes, with automated anomaly detection triggered when RTT exceeds 4x the historical baseline.
