I noticed last week that my BOINC client wasn't connecting to the Rosetta @ Home server to report completed Work Units. I emailed David Baker, manager of the R@H project and this evening received a reply:
Very unfortunately, we had to move the servers from one location to another, and it is taking much longer than we thought to get everything back up again. We hope to have this complete in the next day or two. Please do notify the community that we are working as hard as we can on this, and we thank everybody for their patience. We have a big set of exciting jobs we will be sending out as soon as everything is up and running.
So hold tight everybody, R@H hasn't disappeared - just hold tight and wait for the server migration to finish.
