Explanation of classification scheme

ProgClub classifies its machines as either user machines, or administrative machines.

User machines are systems that ProgClub members can log into for programming or account usage purposes. Member web-pages are available via user machines.

Administrative machines are systems that are used to provide administrative services such as the ProgClub web-site, user authentication, user home directories, email, or administrative databases.

The canonical domain for user machines is, whereas the canonical domain for administrative machines is The reverse DNS lookup for hosts on the ProgClub network uses the appropriate canonical domain. It is generally best to use the canonical domain names, however you can use other domain names as explained in Domains.

A note on virtualisation

At the moment all ProgClub machines are virtual machines provided by Slicehost. They can be a little slow, sorry about that. Maybe one day ProgClub will have enough funds to get some real boxes, but at the moment we can only afford these limited-capacity virtual machines. If you're experiencing capacity issues with any of ProgClub's machines, get in contact with John and we can look at system upgrades. These cost money though, and there's no point spending money on unused capacity. There was an issue with slowness of the ProgClub web-site, which has been resolved by a system upgrade.
