Biznet Nusantara Cable System-1 (BNCS-1)

Biznet Nusantara Cable System-1 (BNCS-1) is a domestic submarine cable network within Indonesia, connecting 4 coastal and island locations including Anyer, Kalianda, Muntok, Sungsang. 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. GeoCables tracks this cable using RIPE Atlas measurements from four probes in Minsk, Almaty, Tbilisi, and Jerusalem, comparing live RTT against historical baselines to catch performance shifts early.
