Echo

Echo is a cross-regional submarine cable connecting Guam, Singapore, United States, Palau, Indonesia. Its 6 landing points at Agat, Changi North, Eureka, Ngeremlengui, Piti, and 1 more bridge the networks of Oceania, Southeast Asia, North America, providing an important path for international data traffic. As an intercontinental system, Echo plays a role in the global mesh of over 500 submarine cables that collectively carry more than 95% of international data traffic. 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.
