Since 2006, this data center facility has provided access to more than 40 of the leading domestic and international carriers and physical connection points of the world's telecommunications networks and Internet backbones.

Located in the South Loop of the Chicago Central Business District, 350 E. Cermak is the premier mission critical interconnection, colocation and telecommunications facility in the Midwest. The facility offers access to the CME/LNET Exchanges, direct access to SFTI Network and other carriers via fiber to the other suites within the building.
