What changes the reading

  • The filing describes two one-story buildings with the same internal layout. Its budget and area cover the pair together, so this page does not divide either figure between them.[2]
  • Review complete is the construction register's accessibility review status. It does not establish that construction finished or that either building is serving computing load.[2]

Still not public

  • Current construction status is not public.
  • Planned information technology load is not public.
  • Water use and cooling design are not public.
  • The filing does not divide cost or area between the two buildings.

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.
