Data Center Campus
Stack: Alpharetta ATL01 Campus
STACK Infrastructure's ATL01 campus covers 18 acres on Webb Bridge Road in Alpharetta, Georgia, in the GA-400 tech corridor. T5 Data Centers built the first building and sold it to STACK in 2019. First built in 2011, with expansion planned through 2028.
Campus at a Glance
STACK Infrastructure's ATL01 campus sits at 3200 Webb Bridge Road in Alpharetta, in north Fulton County, in the GA-400 / North Point office corridor.
Land. The campus covers about 18 acres on two parcels. The 12-acre original parcel is titled to the Development Authority of Fulton County under the bond-lease that financed the first building; the authority issued $160 million in taxable bonds for the project in 2011. A STACK affiliate (SI ATLL2 LLC) bought the adjacent 6-acre parcel for a second building, which STACK announced in May 2020.
History. T5 Data Centers developed the site as T5@Atlanta, its first Atlanta-area data center. Insurer Unum signed as the first tenant in 2012. IPI Partners folded the facility into STACK Infrastructure when STACK launched in January 2019, and STACK renamed it ATL01.
Infrastructure. Georgia Power serves the campus through its "Hi-Reli" dual underground feed. T5 described five substations able to feed the site, two of them on the Hi-Reli system, with concrete-encased 25 kV feeds and an on-site automatic transfer switch. Backup power comes from 2.5 MW Caterpillar diesel generators in a 4:1 reserve-redundant layout. Cooling is chilled water with water-side economization.

Developer
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.
