Last Sunday (2010/07/04) Debuntu server ran into some issues and got offline for some time.
It appears that one of the Raid disk got almost dead and processes were getting stuck in IOwait state.
Anyway, data was safe and everything could be recovered from the disk.
Debuntu used to be running on a Debian Etch box, but Etch just got out of support not too long ago, so I took the opportunity to re-install from scratch a new Debian Lenny.
After some hardcore [rsyncing](https://www.debuntu.org(/how-to-copy-files-over-the-network-and-preserve-file-permissions-and-informations-with-ssh-and-rsync/) everything is up again.
Now, hopefully, the server should be running smoothly so some times :).
