Telxius Opens Cancún Gateway Ahead of Its Unfinished Cable
MEXICO · INFRASTRUCTURE
Key Facts
- —What’s finished: Telxius’s new Cancún Landing Gateway and Edge Data Center is complete and ready for customers.
- —What’s not: The Tikal submarine cable it was built to serve is not due until the first half of 2027.
- —The route: Tikal will run from Puerto Barrios, Guatemala, via Cancún, to Boca Raton, Florida, in the United States.
- —The builders: Telxius built the Cancún branch alone; the wider Tikal trunk is a joint project with América Móvil.
- —The capacity: Telxius puts the main trunk’s initial capacity at about 380 Tbps.
- —The bigger picture: Telefónica and Pontegadea, Telxius’s owners, are seeking buyers for its whole submarine cable business.
Telxius has finished a new cable landing station and data centre in Cancún, Mexico. The submarine cable it was built to serve is not due until 2027.
Cancún’s new facility is complete. Telxius calls it a Landing Gateway and Edge Data Center, and says it is ready to take on customers now.
The cable it was built for is a different story. Tikal, the submarine system due to land there, is not expected until the first half of 2027.
Boca Raton sits on Florida’s coast, making it a US landing point for the new cable. The Caribbean has relatively few redundant cable routes, so extra ones give operators more options if one is damaged.
That gap says something about how this kind of infrastructure gets built. The landing house goes up first, well before the ship that will use it arrives.
What a Landing Gateway Does
A submarine cable comes ashore at a landing station, where it is spliced into terrestrial networks. Cancún’s version adds something newer: computing capacity built into the same site.
That is the edge data centre part. Processing can happen close to where the cable lands, rather than being sent further inland first.
Telxius describes the facility as carrier-neutral, meaning it belongs to no single network operator. Any carrier can interconnect there on equal terms.
It also cites Tier III standards with N+1/2N redundancy for power and cooling. In practice, that means maintenance and repairs can happen without shutting the site down.
Telxius calls the whole facility AI-ready, a marketing phrase with no fixed technical meaning. Tier III and N+1/2N, by contrast, are defined engineering standards.
Tikal, the Cable It Was Built For
Tikal will run from Puerto Barrios, Guatemala, with a landing at Cancún, to Boca Raton, Florida. It is due for service in the first half of 2027.
That date has already slipped. When the Cancún extension was first announced in October 2023, Telxius targeted mid-2026.
Telxius puts the main trunk’s initial capacity at about 380 Tbps, up from an initial 190 Tbps estimate. For comparison, ARCOS-1, the older cable that already serves Puerto Barrios, was designed for about 8.4 Tbps.
CELIA, another Caribbean cable Telxius is building toward Boca Raton, is rated above 170 Tbps. ARCOS-1’s US landing is North Miami Beach, not Boca Raton, so it does not share Tikal’s exact route.
Telxius’s release calls Tikal the highest-capacity cable on that specific route, which no other cable appears to share. That comparison could not be independently confirmed either way, so this piece states only the capacity Telxius has published.
The wider Tikal system began in January 2023 as a joint project between Telxius and América Móvil. Telxius later took on the Cancún branch alone — a partnership this particular release never mentions.
The cable itself is being supplied by Alcatel Submarine Networks, which has also built CELIA and several of Telxius’s other recent systems.
Why Route Diversity Matters
Submarine cables carry more than 99% of international data, including the traffic behind everyday streaming and cloud services. Globally there are around 500 of them, and the industry logs more than 200 cable faults a year.
The Caribbean is more exposed than most regions. Hurricanes, seismic activity and heavy shipping traffic all threaten the same narrow corridors that cables must pass through.
An international submarine-cable resilience summit in Porto, Portugal, in February 2026 was organised by Portugal’s regulator with the ITU and ICPC. The Caribbean Telecommunications Union, reacting afterwards, called geographic redundancy “foundational to economic continuity, digital public services and national security” for Caribbean states.
Guatemala’s Caribbean coast is not new to this. ARCOS-1, a cable in service since 2001, already links Puerto Barrios to the US and more than a dozen other countries.
That is a reminder of how few, and how old, some of the region’s existing routes still are.
Where It Fits in Telxius’s Network
Cancún does not stand alone. Telxius already runs SAm-1, connecting the US with Central and South America, and PCCS, its Pacific Caribbean route.
It also operates a landing gateway in Punta Cana, Dominican Republic, and recently expanded its network in Santo Domingo. CELIA, a separate cable also due in 2027, will add landing points in Puerto Rico, Aruba, Antigua and Martinique.
From Cancún, Telxius also offers an alternative terrestrial route to Santiago de Querétaro, in central Mexico. That gives customers a second path inland if the coastal route is disrupted.
Who Owns Telxius
Telxius is majority-owned by Telefónica, the Spanish telecoms group, which holds 70%. The remaining 30% belongs to Pontegadea, the investment vehicle of Zara founder Amancio Ortega.
The two bought out a 40% stake previously held by KKR in 2022. Telxius describes its network as spanning more than 100,000 kilometres (62,000 miles) of subsea and terrestrial fibre.
In July 2026, Telefónica and Pontegadea said they were seeking buyers for the whole of that submarine cable business. Market estimates put its value at around €1.2 billion, with financial advisers already contacting potential buyers.
It is not clear whether Cancún and Tikal would be included if a sale goes ahead. A new owner is, in principle, a live possibility for the network this facility joins.
What the Announcement Leaves Out
Telxius’s announcement leaves several ordinary questions unanswered. It gives no investment figure, no floor space or power rating for the data centre, and no staffing numbers.
Nor does it name an opening date for the facility beyond the date of the release itself. Those gaps are not filled in here with estimates.
