The record, newest first

  1. Texas Public Radio reported the $65 million Donop Road project as part of a wave of new San Antonio-area data centers. (Texas Public Radio, March 18, 2026)

  2. Amazon registered a $65 million, 119,407 sq ft two-story single-tenant data center building at the same address, with work scheduled from December 2026 to February 2029. (Texas Department of Licensing and Regulation, March 15, 2026; DatacenterDynamics, undated)

  3. Amazon Data Services registered an $18.6 million fit-out of a new data hall inside an existing data center building at 12807 Donop Road; the state inspection is complete. (Texas Department of Licensing and Regulation, Sept. 6, 2024)

Conflicts and open questions

  • sqft is the sum of the 33,411 sq ft fit-out area and the 119,407 sq ft new building; the full size of the existing building is not in the records.
  • Coordinates are approximate, from the Donop Road corridor.
  • DCD reports Amazon bought the property in October 2020 under the name 'Rockfish', which is also the facility name in TDLR.

The full record

Status note
TDLR shows a data hall fit-out in an existing data center building with inspection complete (Nov 2025), and a second two-story building registered for construction from December 2026. Amazon does not list the site as live, so it is not marked operating.
