Hmm. Looks like its gone down again? And again... Seems fishy... Very. Is it possible that some resource on the haskell.org server isn't accessible but also doesn't time out when requested? I've seen things like that with samba shares where the requested file is never fetched and the process pretty much goes to sleep until it is fetched. Just an idea.

I've noticed this happen several times in the past. It would have 150 hung connections but not very high cpu or network usage. On those occasions I restated httpd to get things going again. Looking at the httpd access logs it looked to me like an errant indexing bot. One example of something we might want to ban bots from is from accessing all past revisions and diffs of wiki pages. But generally we probably just need to look at the logs and try and see what's going on.
