Conflicts and open questions

  • Phoenix 4 is matched to the Hermosa Ranch purchase by location (QTS address sits just west of Avondale Blvd on Lower Buckeye Rd); QTS does not state the acreage on its page.
  • Acreage figures differ: 239 acres (city case), 234 acres master plan, 212 acres for the data center portion, 206 acres purchased.
