Trans Global Cable System (TGCS)

Trans Global Cable System (TGCS) is a domestic submarine cable network within Indonesia, connecting 7 coastal and island locations including Balikpapan, Batam, Ketapang, Makassar, Manado, and 2 more. The system provides essential telecommunications infrastructure for communities that would otherwise depend entirely on satellite or microwave links. Indonesia, the world's largest archipelago with over 17,000 islands, relies heavily on domestic submarine cables to connect its geographically dispersed population. 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.
