Opposition and litigation at this site

Nothing on record as of September 15, 2026. No lawsuit, organized opposition, or contested hearing over Iron Mountain Boston Data Center (BOS-1) in Northborough, Worcester County, Massachusetts appears in the sources this registry tracks.

A new status, a permit, a reception finding, or a lawsuit. Nothing else, ever.

Power and water

Facility power is "matched by 100% renewable energy" per the operator (renewable energy matching/certificates against grid draw, not confirmed on-site generation).

Operator states a "waterless cooling design", no cooling-water circuit at all, so classified air per the contract's cooling-type tie-breaker.

Notes on the record

22,000 sq ft building on a 58.3-acre campus; LEED Gold certified and rated to withstand Category 4 hurricane winds; operator states a dedicated dark-fiber link to Boston's 1 Summer Street carrier hotel. "Currently provides 1.2 MW operationally, with 3.6 MW of total potential critical power capacity", recorded as operational 1.2 / planned 3.6.

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

  • Tax abatements or other public subsidy
  • Permanent jobs promised
  • How the community has received it
  • Which utility serves it
Which document closes each gap
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
The economic development application or incentive agreement, which usually states a job commitment and a clawback.
How the community has received it
Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
Which utility serves it
The electric service agreement or the utility's filing with the state public utility commission.
