Summary

TierPoint's Chicago page, in its version modified on 3 September 2026, says 'Just west of the Loop in the heart of Chicago, the state-of-the-art TierPoint Chicago (Polk St.) data center and colocation facility enables companies in many industries to increase business agility' and that the Chicago area hosts one of TierPoint's multitenant cloud pods. It gives 601 W Polk St, Chicago, IL 60607, 107,000+ total square feet, 16,000+ square feet of raised floor, two 2.25 MW redundant generators, DWDM connectivity to 350 E Cermak, 24x7x365 on-site security and 24x7 remote hands. This records the facility as operating on 3 September 2026, the modification day of the captured version (bounded below by the Internet Archive copy of 15 July 2026 and above by the 26 October 2026 capture); it is not an opening date, and generator ratings are not IT load. evidence

Location details

Coordinates: 41.87160, -87.64307
Geometry licence: public-record-source-terms
Use scope: Project locator
Scope class: official_tax_parcel_centroid
Authority: Official source
Source entity: Campus
Method: official_county_assessor_published_parcel_centroid_of_operator_address
Derivation: direct_geometry
Precision scope: Cook County Assessor's published parcel centroid for PIN 17163100010000 (601 W Polk St; tax years 2024-2026), which coincides with the centroid of the parcel's 2021 GIS polygon (1.465 geodesic acres, about 98 by 62 m). It locates the data-centre building's parcel, not a surveyed footprint.
Horizontal uncertainty: Not reported
The Assessor publishes no positional accuracy for parcel centroids; the point represents the whole 1.46-acre parcel, and the position of the data-centre space within the building is not published.
Geometry evidence: 80fc3e25

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
