= C =
co-lo /koh'loh`/ n.
[very common; first heard c.1995]
Short for `co-location', used of a machine you own that is
physically sited on the premises of an ISP in order to take
advantage of the ISP's direct access to lots of network bandwidth.
Often in the phrases `co-lo box' or `co-lo machines'. Co-lo
boxes are typically web and FTP servers remote-administered by
their owners, who may seldom or never visit the actual site.
