Southeast Asia-Japan Cable 2 (SJC2)

Southeast Asia-Japan Cable 2 (SJC2) is a major intercontinental submarine cable system spanning 7 countries across East Asia, Southeast Asia. With 10 landing points — including Busan, Changi South, Chikura, Chung Hom Kok, Fangshan, and 5 more — it forms one of the backbone links carrying international internet traffic between continents. Intra-Asian connectivity is critical for the region's booming digital economy, with data centers in Singapore, Tokyo, and Hong Kong serving as regional hubs. 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.
