hi,
did the trinity git tree change, I cant fetch it anymore...

[jolsa@...va trinity]$ git remote -v
origin  git://git.codemonkey.org.uk/trinity (fetch)
origin  git://git.codemonkey.org.uk/trinity (push)
[jolsa@...va trinity]$ git remote update
Fetching origin
fatal: Unable to look up git.codemonkey.org.uk (port 9418) (Name or service not known)
error: Could not fetch origin

thanks,
jirka
