ProjectColo was set up by a number of ex tardis admins, in order to provide a shared hosting facility and cut costs. The service which was set up by the group is still active, although the group is now relatively dormant due to many members leaving the group and a lack of active interest. The colo system which was used by projectcolo was entitled kerouac, and is now in use in tardis as a rackmount disk server having been donated by kev. Kerouac is now a xen instance running on rose.weegie.net.
