It looks like the Einstein@Home servers are down again. This seems to happen once or twice a month and can last for anything up to a few days.
Looking over the BOINC message log, it appears that the servers may have been kaput since around 0430Z today. Over the last few days there have been occasional problems when my client has tried to connect and download new work units, but this looks like a big one.
At the time of writing, the Server Status page is non-existant and the main project page isn’t coming up (It may have made sense for the Einstein@Home team to have put these on different servers…). The forums, which I thought were on different servers, also seem to be off line at this time.
Oh well. Might as well turn it off then.
