Belize City, Belize

How the Internet Reaches Belize City

Belize City sits on the Caribbean coast of Belize, at the mouth of Haulover Creek where it meets the Caribbean Sea. As the country's principal port and largest city, it is also the primary point where international submarine cable infrastructure connects Belize to the wider internet. International traffic arriving in Belize City does so through a single submarine cable terminus — meaning the city serves as a dedicated landing point rather than a waystation along a longer corridor.

That cable is ARCOS, which lands directly at Belize City and links it to a broad network of Caribbean, Central American, and South American nations. All international internet traffic flowing into and out of Belize City travels across this one physical cable system.

The Cable Serving Belize City

The ARCOS cable — 8,704 km in total length and ready for service in 2001 — connects Belize City to the Bahamas, Colombia, Costa Rica, Curaçao, the Dominican Republic, Guatemala, Honduras, and Mexico, among others. Specific landing points on this cable include Cancún in Mexico, Cartagena in Colombia, Cat Island and Crooked Island in the Bahamas, and Bluefields in Nicaragua. This single system therefore provides Belize City with reach across the Caribbean basin and onward to both North and South America.

Regional Context

Belize as a country hosts 2 submarine cables across 3 landing points. Belize City, with its ARCOS landing, is the most connected of these, while the other two landing points — Bomba and San Pedro — each carry a single cable. The average cable length across Belize's submarine infrastructure is 2,917 km, and ARCOS, entering service in 2001, remains the country's earliest submarine cable connection.

What This Means for Connectivity

Because Belize City is served by a single submarine cable, all of its international internet traffic flows through ARCOS. Any disruption to that cable system directly affects every external service accessible from the city. There is no submarine cable redundancy at this landing point — traffic to and from destinations across the Caribbean, Central America, and beyond all depends on this one physical route.

The countries reachable via ARCOS — spanning Mexico to the north, Colombia and Curaçao to the south, and the Dominican Republic and Bahamas to the east — reflect a primarily regional and inter-Caribbean connectivity profile. Understanding this single-cable dependency at Belize City's landing point is essential to understanding Belize's position within the broader Central American and Caribbean internet topology.
