The record, newest first

  1. At a special meeting, the planning board voted unanimously against extending the 2021 special permit, finding no good cause; members cited the company's lapsed LLC registration and the permit never being recorded at the registry of deeds. (New England Public Media (via Connecticut Public), Oct. 14, 2026; The Boston Globe, Oct. 14, 2026)

  2. The City Council gave final approval to a one-year moratorium on new data centers; the already permitted Servistar project was treated as exempt. (The Reminder, July 16, 2026; New England Public Media (via Connecticut Public), Oct. 14, 2026; The Boston Globe, July 14, 2026)

  3. One of the proposed lots, 191 Servistar Industrial Way, was sold to a local buyer who told The Shoestring he had not known it was part of the project. (The Shoestring, July 2, 2026)

  4. The state House adopted an amendment adding a data center sales tax exemption meant to help the Westfield project, but the economic development bill stalled that summer. (The Reminder, Aug. 11, 2022)

  5. The City Council approved a 40-year tax agreement for Servistar Realties, 10 to 3. (The Westfield News, Oct. 23, 2021)

  6. A $2.7 billion, roughly 2.7 million square foot data center campus of about 10 buildings in a Westfield industrial park entered permitting. (IREI, Aug. 26, 2021)

Conflicts and open questions

  • The planning board met in a special session on Tuesday, Oct. 13, 2026, per NEPM's Oct. 14 report.
  • The Westfield News reports the Oct. 21, 2021, tax agreement vote as 10-3; the Boston Globe reports a 9-3 city vote approving the project in 2021. They may be different votes.
  • Acreage: 162 acres (Westfield News, 2021) vs. more than 150 acres (NEPM, 2026). NEPM says Servistar never bought the land.
  • Possible appeal: Servistar had 20 days under state law to appeal the denial; no appeal was found as of Oct. 24, 2026.
