Project Colo is a computing service for a small group of individuals, hosted in a colocation facility in London. It provides us with facilities for mail, news, web serving and other such activities. Many of these services are for other domain names held by us (so if you are seeing this instead of some other site, our server may be a bit screwed up).
Documentation for our users is provided here, and there are ssh key fingerprints they should check when connecting for shell access. There is also an OpenPGP keyring of Project Colo members, and a certificate authority for use with SSL and TLS connections.
If you need to contact us, our postmaster mail address should be used for matters concerning electronic mail, and our webmaster address for matters concerning our web serving. Complaints should be directed to abuse.
