It worries me when your site goes down.
Any story to tell about it?
There was a problem at the provider... they said a hacker attack. I hope that everything is in place again now, and that not too much email was lost... please send your mails again if you don't get a reply.
The release of RC6 that I did just before the crash was not yet included in the backups, so I repeat the release right now... it should be online in a few minutes.
