I found source.squeak.org was not running properly a while ago. It was only rendering the very top content of the front page and no styling. The most recent backup was from a couple of hours earlier so I tried that first but it had the same problem. So then I tried a backup from about 26 hours ago and now that is up and running.
Any changes made to source.squeak.org project since about 11/8/2012 13:00 UTC will have disappeared. If you did any related work since yesterday you should at least check it.
