Microsoft SAT14 is the phased data-center facility at 3545 Wiseman Boulevard in San Antonio. State records distinguish its two original building shells from subsequent interior fit-outs. Microsoft identifies Walbridge Aldinger as the general contractor and describes construction measures for neighboring residents. The filed March 2026 completion dates are construction milestones, not proof that the facility has entered service.

## Compute and operations

- Operating context: Microsoft's Wiseman Boulevard update describes a datacenter project and distinguishes construction completion from operational availability. Its March 2026 construction estimate is not an energization date. The reviewed records do not establish the facility's current IT capacity or live-service status.
