About the SEAX-1 Cable System

SEAX-1 is a regional submarine cable serving 3 countries: Indonesia, Malaysia, Singapore. With landing points at Batam, Mersing, Tanah Merah, it strengthens regional internet resilience and provides route diversity — crucial when nearby cables experience faults. Submarine cables in this region contribute to a mesh of redundant paths that keep internet traffic flowing even when individual systems are damaged or under maintenance. GeoCables monitors this system's performance through regular RIPE Atlas probe measurements, analyzing RTT patterns to detect degradation before it impacts end users.
