Looks like they got overwhelmed, their servers ran out of WU's two days ago and after an upgrade they still can't keep up the pace it seems: https://foldingforum.org/viewtopic.php?f=24&t=32424
So I will be "donating" simultanously here https://boinc.bakerlab.org/ only with folding@home's priority increased (configure->advanced->folding core priority->slightly higher), so if they do happen to have some WU's free my PC can start working on them. And there is also an LTT group over there https://boinc.bakerlab.org/rosetta/team_display.php?teamid=12242
