This is a source-attributed discovery row. It can help you find a place and its citations; it is not a DataCenterData finding that the facility is distinct or currently operating.

Provider notes
Water. Cooled using a 35-acre underground lake / geothermal cooling system in the former limestone mine; Iron Mountain cites this as the basis of the site's efficiency. No withdrawal or consumption figure is published.
These reviews flag conflicting scope, inconsistent source text or support that has not been established. A withheld value may appear in the explanation, but is not displayed as an established field. The upstream row remains attributed under Sources.
- Cooling: Previously held pending provider-field review. The concern has not been resolved by an independent source review for this captured edition; the field remains withheld.
What the source record says
333,000 sq ft of data center space 220 feet underground in a former limestone mine on a 200-acre campus, about an hour north of Pittsburgh. Operator states 40 MW of total potential capacity; the currently energised load is not published, so the figure is recorded as planned rather than operational. Long-standing colocation/records site rather than an AI buildout — no aiClassification asserted.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
Status history supplied by the source
No status history was supplied in this edition.
Sources and attribution
These sources are listed for the whole row. Unless a figure links to its own source, the provider does not mark which one gave it, so a figure may not appear in every source.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
