What changes the reading

  • The air review treats Westover Link as a three-building campus. The construction register has separate filings for the first two buildings, while the same air review says equipment for the third had not been installed in its snapshot.[3][4][5]
  • Inspection complete on the first construction filing is an accessibility review status. It does not establish occupancy or service.[3]

Still not public

  • The current operating status of each building is not public.
  • The campus's information technology load is not public.
  • Water use and cooling design are not public.
  • A separate construction filing for the third building was not found.

The registry entry for this facility comes from the Texas Comptroller's certified list of data centers holding a sales tax exemption. Owner, occupant and operator are roles in that filing rather than descriptions of who runs the building.
