SEA-US

SEA-US is a major intercontinental submarine cable system spanning 6 countries across Southeast Asia, North America, Oceania. With 7 landing points — including Davao, Hermosa Beach, Kauditan, Magachgil, Makaha, and 2 more — it forms one of the backbone links carrying international internet traffic between continents. As an intercontinental system, SEA-US plays a role in the global mesh of over 500 submarine cables that collectively carry more than 95% of international data traffic. GeoCables maintains health checks on this cable using distributed RIPE Atlas probes, with automated anomaly detection triggered when RTT exceeds 4x the historical baseline.
