Same thing has happenned to our site - it's gone back in time about a month!!!
However, some hope can be gleaned from the fact that Roger at ModCentral (also hosted here) said the same thing happenned to them - but now they seem to be back up to date.
So, here's hoping he didn't have to restore his site from a personal back-up... (which I didn't think to make - but will make DAMN sure I do in future...!)
