CyrusOne announced it has broken ground on its fifth data center campus at the Texas Research Park in San Antonio.

The data center operator announced the news on LinkedIn this week.

Plans for the campus were first announced in November last year.

At the time, the project was said to span 279,730 sq ft (25,990 sqm) and include four data halls. Construction was expected to start in April this year and be completed by December 2025.

Dallas-based CyrusOne operates a number of data centers in San Antonio, currently listing three on its site: the 9MW SAT1 at 9999 Westover Hills Blvd, the 36MW SAT2 at 9554 Westover Hills Blvd, and the 18MW SAT5 at 14719 Omicron Drive. The new project is located directly south of CyrusOne’s SAT5 facility.

Microsoft operates a large campus nearby at 15000 Lambda Drive. The company completed another 79,385 sq ft (7,375 sqm) data center at the Texas Research Park campus, known as SAT46. At full build-out, the site will total more than 1 million sq ft (92,900 sqm).

A number of companies are also building facilities nearby. Vantage, QTS, and CloudHQ have all acquired land along Omicron Drive and Lambda Drive, close to Microsoft’s campus.
