Community.haskell.org is a server in our ecosystem that comparatively few know about these days. It actually was, to my knowledge, a key part of how the whole haskell.org community infrastructure got set up way back when. The sparse homepage still even says: "This server is run by a mysterious group of Haskell hackers who do not wish to be known as a Cabal, and is funded from money earned by haskell.org mentors in the Google Summer-of-Code programme." At a certain point after this server was created, it ceased to be run by a "mysterious group of Haskell hackers" and instead became managed officially by the haskell.org Committee that we know today. You can see the original announcement email in the archives.
This past week, the primary Haskell.org server hosting the wiki and mailing systems went down due to RAID failures in its underlying hardware. Thanks to some (real) luck and hard work, we've managed to recover and move off the server to a new system, avoided some faulty hardware, and hopefully got some improved reliability.
