OSM way/128499684 · operator tag: Digital Realty

WAPR is a public register of where AI computing physically sits. This page is one building that volunteers have mapped as a data centre — the map records what kind of building it is, not what runs inside it, so it may host AI, cloud or ordinary corporate servers. Everything below comes from OpenStreetMap, the volunteer-made public map, and is republished as recorded — including the operator tag, which is what mappers entered rather than a check of who runs the building today. Fields nobody recorded are shown as “not recorded”, never guessed. What WAPR is →

This record is what OpenStreetMap contributors have mapped and tagged as a data centre — nothing more. WAPR republishes it verbatim with provenance; fields the mappers did not record are shown as such, never inferred.

What the public record says

Each line marks a step in this site’s life — a rung, in the register’s terms — with the public document that records it, its date and what kind of date it is: the document’s own, a state the record shows already held on that date, or the day WAPR first saw the record. Where three or more lines would differ only in their distance from the pin — the same step, source and date — they share one line, and each record is listed under it.

1. 2026-03-06on or beforecrane notices filed beside it — FAA obstruction evaluation case file: the first filing within 1 km of any register object of this crane site (the objects sharing its name, operator and country, each within 3 km of another member), one calendar-year window (0 m from the pin)
   4 filings within 1 km, last 2026-10-08
   FAA case files are read one calendar year at a time and the 2025 FAA year file was joined against a different register than the 2026 file the crane dates come from, so a filing near an object one register lacks cannot be counted — re-derive it (collectors/faa_part77.py --rederive 2025), so the first 2026 filing cannot be shown to be when this site's filings began

   Each by the name and organisation PeeringDB lists for it (the PeeringDB list WAPR serves, generated 2026-09-14), nearest first. The names are PeeringDB's own; WAPR does not title this building from them. Interconnection facilities: Colocation and interconnection sites that network operators register publicly. Enrichment only — it over-represents colo and under-represents hyperscale.

The register’s rungs are: mapped · listed in the network registry · crane notices filed beside it · on an air regulator's books · holds a discharge permit · generators recorded emitting · a generator within 250 m produced power · interconnection · operating load. Rungs not shown for this site are rungs no public document has put it on. Interconnection and operating load are never written until a primary record exists.

Straight-line joins to federal layers: HIFLD transmission and retail service territories (2023 vintage), USGS principal aquifers (1:2.5M), USGS NHD named flowlines. They say what surrounds the site, never what it draws, pumps or discharges. A territory says who sells retail power there; a line passing a site is not a line serving it.

Air permit

No air-permit source is linked to this site; 2 within 246 m are credited to WAPR-US-001472. Each source is credited to one mapped site, so one that covers this site may be listed under a neighbour. WAPR reads only the ICIS-Air sources a state has coded NAICS 518210 or SIC 7374, so this is not proof the site has no permit.

Emissions on record

No NEI 2023 facility is linked to this site; 2 within 359 m are credited to 2 other mapped sites. 2,889 point facilities in Illinois are in the 2023 file, 2,338 with state, local or tribal agency data, 16 of them read by WAPR's filter as data centres with NOx. ICIS-Air lists 41 Illinois sources under the data-processing codes, 27 carrying an EIS id, 13 of those ids in this file. The file does not say whether a site missing from it fell below the reporting threshold or was not submitted, and WAPR reads only the facilities its filter selects — the filter is under How this is known.

Water discharge

No discharge permit coded to the data-centre sector within 500 m. Most cooling water leaves as vapour and to the sewer, not through an outfall, so a site with no discharge permit on record is not a site that uses no water.

Generators within 1 km (EIA)

No EIA-listed generator within 1 km. EIA lists grid-connected units of 1 MW or more; behind-the-meter plants that never interconnect are not obliged to file.
