Jeju-Udo

Jeju-Udo is a submarine cable system operating within South Korea, with landing points at Goseong-ri, Udo. It provides dedicated submarine fiber capacity between these locations, supporting telecommunications, internet access, and enterprise connectivity. 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 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.
