South Atlantic Inter Link (SAIL)

South Atlantic Inter Link (SAIL) is a point-to-point submarine cable linking Brazil and Cameroon. Landing at Fortaleza, Kribi, it provides a direct fiber-optic path between the two countries, serving as both a primary data route and a redundancy option for neighboring cable systems. As an intercontinental system, South Atlantic Inter Link (SAIL) 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.
