n. A building designed to hold only telecommunications equipment.

Example Citation:
"Unlike the company's other buildings, the six-story, 500,000-square-foot structure is not intended to house people. Instead, it is being designed for machinery, the servers, routers and switches that are the physical underpinning of the rapidly growing electronic commerce being conducted on the Internet....It is a new type of property known in the industry as a telecom hotel, because it houses equipment belonging to many different telecommunications companies."
—John Holusha, "Home for Machinery of the Internet," The New York Times, August 16, 2000
