Storage machine crash....
A machine that was holding 15% of our outgoing workunits has crashed and refuses to start back up. Short term it means that attempts to access those workunits will cause an error until the workunit is marked as bad.

Sorry for the incovenience.

Slow server for the next 8 hours or so...
GeorgeM, the machine that holds the data that you download, decided that it was time to verify that the RAID array is in good shape. That will slow down disk access until the verify procedure is complete. The main effect is slowing down the rate at which work can be created. It's likely that we'll run out of work in the next hour or so. Things should recover automatically when it's done.

Little bits of previously unfinished data.
You may have noticed occasional bits of data from years past showing up in your queue. While running a completeness check I noticed some files that had never been completely analyzed. Some may have fallen through the cracks. Some may just be bad data that never made it through the splitters. I'm going to trickle them into the queue when the Arecibo queue is empty, just in case.

Science database crash...
We had a minor science database crash today that brought work generation to a halt. Everything appears to be OK with no data losses. We should [be] entirely back up at this point, but I'll keep checking things out.

Weekly Outage on Wednesday This Week and Next
Because of the Christmas and New Years Day holidays, our weekly outage will be on Wednesday rather than the normal Tuesday both this week and next.
