Nigeria
Nigeria lands three submarine cables along the Lagos coastline, anchoring West Africa's most populous nation to the global internet — though the retirement of one system leaves the country's international capacity concentrated on two active links.

Cables and landing points
Nigeria's submarine cable connections arrive at a cluster of landing points on the Lagos coast: the Lagos metropolitan foreshore and the Lekki Peninsula, both within Lagos State. This concentration reflects the gravitational pull of Lagos as West Africa's largest commercial hub, but it also means that all documented international cable capacity enters the country through a geographically narrow corridor.
Three cables are documented on the register. SAT-3/WASC, ready for service in 2001 and spanning roughly 13,000 kilometres, was among the first modern submarine systems to bind West Africa into the broader Atlantic cable network. It remains active. The West Africa Cable System (WACS), at approximately 14,500 kilometres one of the longer systems on the continent's western seaboard, adds a second active route. Main One, a 14,000-kilometre cable purpose-built to introduce competitive capacity on the West African corridor, has since been retired from service.
Capacity and resilience
With Main One out of service, Nigeria's documented submarine connectivity rests on two active cables: SAT-3/WASC and WACS. Both are substantial systems, but their combined presence raises a straightforward resilience question. A fault or outage affecting either link reduces the country's international submarine bandwidth by roughly half — and a simultaneous disruption to both would sever Nigeria's documented undersea connectivity entirely, forcing traffic onto satellite or terrestrial alternatives.
The retirement of Main One is relevant here. When three cables were active, diversity was meaningfully greater; the loss of one system tightened the margin. Whether additional cables serve Nigeria beyond those currently documented on this register is a question the register will address as its data is compiled and updated.
Geography and chokepoints
Nigeria's coastline faces the Gulf of Guinea, positioning the country at a natural waypoint for cables running along the West African littoral and extending toward Europe, South Africa, and beyond. That geographic advantage is partially offset by the concentration of all landing infrastructure within the Lagos conurbation. Diverse landing points — spread across different coastal locations — would reduce the risk that a single infrastructure event, whether physical or administrative, could affect all cables simultaneously. As the register stands, Nigeria's cable geography is logically coherent but spatially concentrated.
