Lumos Data Centers’s (formerly DC74) most recent addition to its portfolio, CLT-4, is an 18,000 sq ft facility with 12,000 sq ft of immediately available data center space. Ample fiber providers coupled with substantial and expandable power capacity make this facility an ideal location for companies that must accommodate future growth.

CLT-4 is a secure facility with built-in power redundancies and backup generators. An advanced fire protection system, extensive video monitoring, and secure badge only access make CLT-4 structurally secure and well protected. Additionally, all power and environmental systems are expandable to handle capacity or density needs.
