The record, newest first

  1. Mesa's Design Review Board discussed Amazon Data Services' Project PHX65, two data center buildings on 71 acres on the north side of the 10400-10600 blocks of E. Pecos Rd.; no decision was reported. The year is inferred from the story's image dates. (Independent Newsmedia (YourValley.net), May 2024)

  2. Amazon filed requests with Mesa's planning and zoning board for site plan approval and special use permits (height and reduced parking) for two southeast Mesa data center projects named PHX062 and PHX65. (Phoenix Business Journal (republished by Rose Law Group Reporter), Jan. 11, 2024)

  3. Phoenix Business Journal reported Amazon presubmittal filings with Mesa for two data center halls of roughly 227,000 sq ft each on its 71.3-acre Pecos Road parcel, bought in December 2021. (Phoenix Business Journal (republished by Arizona Technology Council), Sept. 26, 2023; AZBEX, Sept. 29, 2023)

Conflicts and open questions

  • Square footage is the reported total of two ~227,000 sq ft halls.
  • YourValley names the Pecos Road site Project PHX65 and places it on the north side of the 10400-10600 blocks of E. Pecos Rd., which fits the 10464 E. Pecos address; its text also says east of Signal Butte Rd. Its story carries no printed year (May 14, likely 2024).
  • Amazon's second Mesa site (about 43 acres off Elliot Road next to Apple's data center) is a separate campus not in this lead group. No source ties the PHX062 name to a specific site.
  • No MW figure found. Operating status not confirmed.
