The campus continues Microsoft's data center expansion across metro Atlanta, which includes facilities in Douglas County and additional south Fulton sites. The Stonewall Tell Road corridor has drawn growing industrial and data center interest due to available land and power infrastructure access.
The site sits near Stonewall Tell Road's intersection with GA-138, with access to I-85 to the east and I-285 to the north. The area is auto-dependent, with MARTA bus service on nearby Union City corridors.
