Submarine cables in Virgin Islands (U.S.)

The Virgin Islands (U.S.) has 10 submarine cable landing points, with the highest concentration located at St. Croix, which hosts seven of the eight cables serving the territory. Other notable landing locations include Banana Bay, Brewer's Bay, and Frederiksted. These landing points connect the islands to a network of international and regional submarine cables.

The longest cable landing in the Virgin Islands (U.S.) is the South American Crossing (SAC), which spans 20,000 kilometers and has been in service since 2000. It connects the territory with countries such as Argentina, Brazil, and Colombia. The newest operational cable is TAM-1, which became ready for service in 2026, extending 7,200 kilometers and linking the Virgin Islands (U.S.) to destinations including Mexico, Panama, and Colombia. Other cables include the Mid-Atlantic Crossing (MAC), Southern Caribbean Fiber, and Global Caribbean Network (GCN), among others.

The main internet service providers by user base are VI POWERNET, Starlink, and Broadband VI. The Virgin Islands (U.S.) is classified as having moderate resilience, meaning that while multiple cables provide connectivity, the loss of a main station could significantly impact capacity. Eight outages have been recorded by GeoCables in the past 90 days, with the most recent occurring on October 24, 2026.
