Summary

CyrusOne's 9 October 2026 update states that the sound mitigation work previously scheduled at Buildings 2 and 3 is complete. For this record, the permanent rooftop sound wall and chiller-specific sound attenuators retrofit at Building 2 (CHI2), that is completion of the selected retrofit. The additional Building 3 measures announced on 29 September are a separate, continuing scope and are not part of this record; no new data hall or IT capacity is implied. evidence

Location details

Coordinates: 41.79807, -88.24341
Geometry licence: no-open-license-asserted
Use scope: Campus locator
Scope class: official_campus_street_address_locator
Authority: Official source
Source entity: Campus
Method: exact_state_named_campus_address_Census_NAD83_to_WGS84_pyproj_3_8_0
Derivation: official_census_street_address_range_interpolation
Precision scope: Exact source-bound campus address interpolated along Diehl Road. This is not the CHI2 rooftop work site, surveyed building position, campus interior, parcel boundary or construction footprint. The state campus address locates the shared CHI1-CHI3 campus once.
Horizontal uncertainty: Not reported
Census supplies no site-specific accuracy for this address-range interpolation.
Geometry evidence: 24e8b46a 2f63a682 f1342044

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.

Sources are linked, not redistributed; each keeps its own terms. An archived copy is a lookup for the Wayback Machine capture nearest the retrieval date and may be unavailable or differ from what was reviewed. Each hash states what it covers; imported factual records are not publisher-page captures.
