Atlantic Crossing-1 (AC-1)

Atlantic Crossing-1 (AC-1) is a cross-regional submarine cable connecting Netherlands, United States, Germany, United Kingdom. Its 4 landing points at Beverwijk, Brookhaven, Sylt, Whitesands Bay 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. This cable is part of GeoCables' continuous monitoring program — RIPE Atlas probes measure latency around the clock, flagging anomalies when RTT deviates significantly from established baselines.
