As many will readily know the Cosmology@home server dropped out suddenly a week or so ago.

Today they have got a "panic" page up:

The Cosmology@Home server died last week during a power outage. We're currently working to bring it back up. Sorry for the inconvenience!

When the server comes back up, we'll try to award credit to everybody who was unable to upload their WUs during the outage.
