There seems to have been some kind of hardware failure on the crazyguyonabike server. I got up this morning to find a read-only filesystem which pretty much stops me from doing anything. There are some clues in the logs which would seem to point to something in the RAID or disk controller, or perhaps one or more hard drives. I have put a message in to our hosting company to ask when they can look at this. Since it's the weekend (of course) it's possible that it might be Monday before anything really gets done, but I'll post updates here if I hear anything.
