co-location

A server located at a dedicated facility designed with special resources, such as a secure cage, regulated power, a dedicated Internet connection, online security, and online technical support. Co-location facilities offer customers a secure place to physically house their hardware and equipment (as opposed to keeping it in their offices or warehouse, where the potential for fire, theft, or vandalism is much greater). This term also refers to a "colo facility," a data center in an unserved or underserved market (also known as a "second-tier city").
