Just want to add a side note here, that the two most popular CLI wrappers 
(downgrade and downgrader in AUR) are using the web service hosted by Arch 
Linux Chinese Community (archlinuxcn). We are also hosting the service right 
at the day when the old A.R.M was down.

I think we're implementing the services in two aspects: Sébastien is providing 
daily-based folders, which is great to rollback or freeze a system at some 
point, while archlinuxcn is providing API for CLI wrappers to query packages, 
which makes more sense for users using the CLI helpers.

About the server resources:

83G     ./community
70G     ./packages

There were some users from the forums gave us their old backups, so we have 
oldest package back to 2007 here, while packages (not including [testing]) 
from 2011 are generally available for search & download.

For example, a search for kernel26 returns every version down to, 
which was released on 2011-04-17 according to our svn log.

So the resource consumption doesn't look scary at all :) I don't actually have 
a preference on making the service official or not, the current domain "repo-
arm.archlinuxcn.org" looks OK to me as well.
