Siboney is a village in eastern Cuba, situated within the municipality of Santiago de Cuba on the island's southeastern coast. Its coastal position places it at the terminus of a submarine cable that physically connects Cuba to the broader Caribbean and South American internet.
International internet traffic reaches Siboney through a single submarine cable, ALBA-1, which lands directly at this point. As a single-cable terminus, all international data flowing through Siboney travels via this one route. Cuba as a whole connects to the global internet through just four submarine cables landing at four points across the island, and Siboney's ALBA-1 landing represents one of those connections.
The ALBA-1 cable — 1,860 km in length and ready for service in 2012 — links Siboney to Ocho Rios in Jamaica and La Guaira in Venezuela. This single cable provides Siboney's only submarine route for international traffic, carrying data across the Caribbean Sea southward toward South America and westward toward Jamaica. Notably, ALBA-1 also lands at Santiago de Cuba, meaning the cable serves two points within the same Cuban municipality before extending internationally.
Cuba hosts four submarine cables across four landing points. Siboney and nearby Santiago de Cuba each terminate one cable — both being ALBA-1 landings — making the southeastern corner of Cuba a modest but distinct node in the country's submarine infrastructure. Elsewhere on the island, Guantanamo Bay connects to two cables, while Cienfuegos holds one additional landing point. Siboney is therefore one of the smaller terminuses in Cuba's national submarine cable picture, sharing its cable with a neighbouring landing point just kilometres away.
Because Siboney is served by a single submarine cable, all international traffic from this landing point flows exclusively through ALBA-1. Any disruption to this cable directly affects every external service routed through it. The destinations reachable via this infrastructure are Jamaica and Venezuela — providing regional Caribbean connectivity and an onward path into South America through La Guaira.
The ALBA-1 cable, in service since 2012, marked the beginning of Cuba's submarine cable era — the country's first submarine cable connection. Understanding Siboney's role as a single-cable terminus helps illustrate how Cuba's international internet access remains geographically concentrated across a small number of landing points, with southeastern Cuba depending on this one link for its submarine connectivity to the wider world.
