FLAG North Asia Loop/REACH North Asia Loop

FLAG North Asia Loop/REACH North Asia Loop is a regional submarine cable serving 4 countries: South Korea, China, Taiwan, Japan. With landing points at Busan, Tong Fuk, Toucheng, Wada, it strengthens regional internet resilience and provides route diversity — crucial when nearby cables experience faults. 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.
