MAREA

MEDIUM
London ↔ New York

MAREA is a 6,600km transatlantic subsea cable connecting Virginia Beach in the United States to Bilbao, Spain, with a branch to Sopelana. Owned by Microsoft (AS8075) and Meta (AS32934), it carries a significant portion of transatlantic financial and cloud data. Ready for service in 2018, MAREA delivers approximately 65ms latency on the London-New York corridor. Simultaneous BGP anomalies on both owner ASNs are a high-confidence cable fault signal. CableAlert monitors MAREA via Cloudflare Radar BGP telemetry and RIPE Atlas anchor probe latency measurements.
