Microsoft previously filed for two projects under the same name and at the same address in Medina in February 2025, but those projects suggested an investment of $350m each. Construction of those projects was set to begin in mid 2025, and be completed by mid 2027.

SAT93, according to its latest filing with the Texas Department of Licensing and Regulation (TDLR), will be a one-story building on a greenfield data center site located at 381 County Road in Medina. The building will span 245,000 sq ft (22,760 sqm). Construction is hoped to be completed by the end of April 2029.

SAT94 will be located on the same site, and similarly span 245,000 sq ft (22,760 sqm) across one story. The data center will see construction start one month after its brother, and finish one month later also.

Gensler Architecture, Design & Planning, P.C., is the designer for both data centers.

DCD has contacted Microsoft for further information about the project regarding its delayed timelines and changing investment.

Medina is located around 65 miles northwest of San Antonio in Texas Hill Country. Microsoft has a significant footprint around San Antonio, and is regularly expanding with new projects.

In January of this year, it filed for a $400m project in Castroville, a town west of San Antonio, where the company is also developing several data centers.

Across the rest of San Antonio, Microsoft has data centers in operation and development across 3545 Wiseman Blvd, 15000 Lambda Drive, 3555 Westover Link, and 5200 & 5150 Rogers Road. The 5150 Rogers Road site is set to undergo "renovation/alteration" works valued at $5 million, as per a separate TDLR filing. This will include the addition of an "interior archive enclosure within an existing facility. Work includes insulated walls and ceiling, vapor barrier, insulated door with seals, and hardware coordination for rack access. Associated MEP components will be integrated."

Microsoft opened its first South Central US Azure region in Texas in 2008, which offers three availability zones. It also opened a US Gov Texas Azure region in 2017.
