511 Building

The 511 Building is a data center in downtown Minneapolis, a three-story concrete structure with no windows that houses extensive fiber optic networks and telecommunications equipment. The structure is designed to support continuous operations with redundant power systems.

The building was originally founded in 1982 as the Control Data Business and Technology Center and initially served corporate technology needs. A comprehensive renovation in 2003 transformed it into its current form as a specialized data center.

The building serves as a vital connection point for digital communication across the region and links various networks together. Technology professionals view it as a hub for data flow and connectivity, even though it appears unremarkable from the outside.

The building is located near U.S. Bank Stadium and is difficult to enter since it is a closed data center facility. Visitors should not expect access, as it is a secure installation with controlled areas.

The building is known as Minneapolis's largest carrier hotel, a term referring to facilities that house telecommunications networks. It handles a substantial share of Minnesota's data flow, though its unremarkable exterior would hide how critical its role is.
