Citigroup Inc.: Citigroup Frankfurt

Citigroup operates a large data center in Frankfurt am Main, Germany, commonly referenced in public engineering and industry sources as the Citigroup Data Center Frankfurt am Main. Citigroup’s corporate website confirms Frankfurt as Citi’s primary location in Germany, but does not publish a dedicated public facility page for this data center with facility specifications, address, or service details.

Public third party sources describe this site as a flagship sustainability project and an early example of green data center design, including being cited as the world’s first LEED Platinum certified data center.
