Jakarta-Bangka-Bintan-Batam-Singapore (B3JS)

Jakarta-Bangka-Bintan-Batam-Singapore (B3JS) is a point-to-point submarine cable linking Indonesia and Singapore. Landing at Batam, Batu Prahu, Bintan, Jakarta, Pesaren, and 1 more, it provides a direct fiber-optic path between the two countries, serving as both a primary data route and a redundancy option for neighboring cable systems. 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. Real-time monitoring by GeoCables compares current latency measurements from RIPE Atlas probes against baseline data to identify anomalies on this cable route.
