1 Overview

The names in the domain point to a set of machines:

1.1 www

This machine ( responds to the names,, and It is hosted in Germany by Hetzner.

MRTG: All network traffic.

Note: before December 2010 these domains were hosted by at Yale University.

1.2 hackage/darcs/cvs

This machine ( responds to the names,,,, It is a dedicated host in Galois server room.

MRTG: All network traffic, External network bandwidth, Free disk space, System load, Free memory, Free swap, All of the daily graphs.

For more details, see Abbot.

1.3 code/community/planet/projects/trac

This machine ( also responds to the names,,,,, See this message.

The Haskell community server is designed to support and encourage open Haskell-based projects and collaborations of all kinds, provided only that their intention is to contribute something to the community, and that all hosted project content is publicly available. Resources available include:

For information about how to host a project, see

Notes: machine has been increasingly unreliable. Plan to move to a VM host on

MRTG: All network traffic, Free disk space, System load, Free memory, Free swap, All of the daily graphs.

1.4 sparky

sparky - a SPARC T2 donated by (formerly) Sun Microsystems. Kindly hosted by Chalmers but technically owned by Oxford University Department of Computer Science (?).

2 Relation between the services

I'm wondering what the relationship is (if any) between and hosts ghc, the core libs and many others. The server is maintained by Galois. Because it hosts the most central bits of the haskell platform, security is fairly tight and getting an account there is hard. There are very few community members with root privileges. was created precisely to provide hosting to the wider community. It is hosted commercially, paid for by's Google Summer of Code funds. We have several community admins with root privileges.

Should my projects be hosted at darcs or code? It's easy to get an account there via the web submission system:

Is one more blessed/preferred over the other for community projects?

Yes, is preferred.

If my project is currently on darcs, should I migrate to code?

You can if you like, there is no need to do so however. Accounts on are not going to be revoked as far as I know. The community server is an addition, not a replacement.

If I have an account on darcs, will it work on code, or do I need to get a new account on code?

They are totally separate systems.

3 Policy on adding new subdomains

We limit the addition of new subdomains to to minimise unnecessary proliferation of subdomains and to try to keep the domain reasonably well organised, while still helping people do useful things with it.

The current policy is that new subdomains are to be used for services rather than content.

So for example a Haskell graphics related website should normally go at, rather than

In contrast a service like hackage does merit its own subdomain.

Clearly the line between services and content, and indeed the precise definitions of each, is something of a grey area, and we are certainly happy to be flexible particularly if there are technical or other reasons for doing things one way.
