STACK's CHI01 campus sits on a single 14-acre parcel on the south side of Touhy Avenue in Elk Grove Village, Illinois, in the O'Hare data center cluster northwest of Chicago. SI CHI01 ABS LLC, a STACK entity, owns the land.

History: Forsythe Technology broke ground on the first building in 2014 for its Retail+ colocation business. The building earned Uptime Institute Tier III certification as a constructed facility. T5 Data Centers bought the property in a 2016 sale-leaseback that kept Forsythe as anchor tenant. IPI Partners acquired it in 2018 for about $119 million and folded it into STACK Infrastructure in 2019.
Expansion: STACK announced a second, two-story building on the adjoining four acres in 2019. The two buildings now stand side by side.
Utility: ComEd serves the campus through diverse underground feeds from smart-grid substations. STACK says one of them is a priority-1 substation that also serves O'Hare International Airport.
Connectivity and incentives: Seven carriers are on campus. In 2019 STACK became the first operator to qualify for Illinois's data center sales-tax exemption.
Tenants: Cyxtera ran its ORD3 suites in the first building until it left in 2023.

STACK's CHI02 project at 1850 Howard Street, about 1.3 km to the northeast, is a separate campus.

Operating Company

STACK Infrastructure is a privately held platform sponsored by IPI Partners that focuses on large scale wholesale capacity and campus development for hyperscale and enterprise customers.

The company was launched in 2019 when IPI combined the remaining Infomart Data Centers assets with selected T5 Data Centers facilities, and industry coverage at launch cited eight data centers across six U.S. markets totaling about 100 MW. In March 2022,

IPI unified DigiPlex in the Nordics and SUPERNAP Italia in Milan under the STACK brand to form STACK EMEA, expanding the platform across Europe. STACK has since added international sites, including the first phase of a 56 MW campus in Toronto and its first Australian data center in Melbourne. Core services referenced by the company and trade press include wholesale colocation, build to suit, and powered shell solutions.
