Conflicts and open questions

  • The lead called this 'Dallas VIII'; no source opened uses that name, and the match to this campus is by location only.
  • DataCenterHawk estimated 72 MW for DC1; QTS has not confirmed power, so mw is left empty.
  • Reporting places this campus in Lancaster; state filings give a Wilmer address on Mason Road.
