Polar Express

Polar Express is a domestic submarine cable network within Russia, connecting 10 coastal and island locations including Amderma, Anadyr, Dikson, Nahodka, Petropavlovsk-Kamchatsky, and 5 more. The system provides essential telecommunications infrastructure for communities that would otherwise depend entirely on satellite or microwave links. 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.
