I don't think many of us crunch there (or at least not often), but Asteroids@Home has been down for about 6 weeks while they await new server hardware. Supposedly they will be getting the hardware in Sept. or Oct. and then relaunching when everything is ready. I was attempting to push my contribution over 1 million credits and unfortunately got caught out with a load of completed work that is now stuck in my BOINC client.
