AFAIK mphq and the latest roundup failure where caused by DoS that becomes
harder not easier if there are multiple targets.
Besides when one of the 3 (fate, roundup, mphq) where down the others still
where up and useable, where all on a single server even if that failed just
1/3 as often i belive that would have been more disruptive.
also having all on a single server means an exploitable hole in one of (fate
roundup/python, svn) could take more down then when they are spread.
Besides this raises the issue of what the admin of that server would
allow to be installed due to security of that one and important server

fate needs someone to admin it, roundup needs someone to admin it,
svn, ftp, ... needs ...
that is where the bulk of work is and that doesnt increase with
them being spread on multiple servers.
The once in 3 years hw failure per server is not a big cause of work
also we have the manpower for the servers we have, i dont see what we
could gain from putting things on a single server, it seems simply a
bad idea to me.
