Turks and Caicos Islands
Turks and Caicos Islands connects to the global submarine cable network through a single documented system, ARCOS-1, leaving the British Overseas Territory with limited redundancy and considerable exposure to network disruption.

A Slender Thread to the Global Network
Turks and Caicos Islands sits at the northwestern edge of the Caribbean, a scattered archipelago of low-lying cays positioned between the Bahamas and Hispaniola. That geography places the territory within reach of the submarine cable routes that lace the Caribbean Basin, but proximity to busy cable corridors does not automatically translate into well-served connectivity.
A single system, ARCOS-1, is the only submarine cable documented as serving the islands. ARCOS-1 is a ring-topology cable that links a broad sweep of Caribbean island and Central American territories to the United States, forming one of the more extensive regional cable systems in the basin. Its ring architecture does offer some internal redundancy — traffic can route in either direction around the loop — but from the perspective of Turks and Caicos Islands, the territory remains dependent on a single cable system. Any fault or capacity constraint on that one link has direct implications for the islands' internet access, voice services, and the data connectivity that underpins financial services, tourism operations, and government functions.
What Single-Cable Dependency Means
For small island jurisdictions, a single submarine cable is a common condition rather than an anomaly, but it is not a comfortable one. Diversity — meaning two or more independent cable systems landing on separate routes with separate shore-end infrastructure — provides a meaningful buffer against outages. Where that diversity is absent, operators typically rely on satellite capacity as a fallback, though satellite links carry higher latency and lower throughput than fibre alternatives.
No specific landing point for ARCOS-1 in Turks and Caicos Islands is documented in the Coral Sea Cables register. Confirming the precise landing location, the associated terrestrial infrastructure, and the parties responsible for that landing station would clarify how traffic actually enters and exits the island chain — details that matter when assessing the practical resilience of the link.
Geography's Role
The dispersed nature of the Turks and Caicos group — two island clusters separated by the Caicos Passage — means that internal connectivity between the islands is itself a logistical question distinct from international access. Getting traffic from one cay to another, and then onto an international cable, adds layers of infrastructure that may or may not be fully documented.
The Coral Sea Cables register for Turks and Caicos Islands is being actively compiled. Operators, carriers, or landing station owners with knowledge of cable infrastructure in the territory are encouraged to contribute.
