Telmex to Build New Data Center in Northwestern Mexico

Telmex announced the construction of a new data center in northwestern Mexico, with construction scheduled to begin next year. This facility will become the company's sixth such infrastructure in the country, designed to meet the growing connectivity demand from companies and users.

The decision responds directly to the increased demand for processing capacity and connectivity, driven by the adoption of emerging technologies like AI and the accelerated digital transformation of productive sectors. 

"[The new data center] will undoubtedly reinforce all the connectivity demand that the sectors require for all the digital transformation and that of the entire country," says Héctor Slim, CEO, Telmex.

Data centers constitute critical infrastructure for the contemporary digital economy. These centralized physical spaces host, process, and manage information generated by a multitude of services, including web searches, social media platforms, financial transactions, and streaming media. The adoption of AI places additional, significant pressure on this infrastructure. AI applications, as Deloitte emphasized, require substantially more computing and storage capacity compared to traditional workloads, translating to a high demand for greater bandwidth and lower latency.

The new northwestern facility will join the five data centers Telmex operates in Queretaro, Monterrey, Guadalajara, Cancun, and Mexico City. The five operational centers account for a total of 85,000m2. These facilities require an aggregate energy capacity of about 70MW to function, reports the company.

The need for this expansion aligns with the company's client base. As of the end of the 3Q25, Telmex reported 11.8 million residential users, solidifying its position as the fixed-line services company with the largest subscriber base in the country. In the business segment, the company serves 800,000 SME clients through its cloud services, a sector that demands high availability and secure networks.

Additionally, the company invested MX$4.01 billion (US$215 million) in its fiber optic network and fixed-service infrastructure during the same quarter. However, this figure represented an 18.9% reduction compared to the capital invested in the same period last year. The company's total network now consists of 650,000km of fiber optics.

Telmex's infrastructure strategy also includes submarine cables. The company operates 18,000km of cables in the Pacific Ocean to manage customer data traffic robustly. "The submarine cables allow us to ensure all connectivity for the next 20 years with all the data demand that our clients from all over the continent might have," Slim says.

The company recently invested US$25 million in the TMX5 submarine cable project, aiming to deploy a 383km fiber optic network. This project "consolidates the telecommunications infrastructure in our country, while also addressing, through connectivity, the economic and development needs [of Baja California Sur],” says Slim.
