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.
