Izzy took a digger again.
It looks as if the main drive is rapidly failing and needs to be replaced. Unfortunately there was no warning of pending drive failure and when the drive goes south, there is not much we can do but replace it. Normally we would do this in the middle of the night not during business hours on a Monday but the drive is completely dead so it needs to be replaced. Any of you who have replaced a primary hardrive and installed an operating system know that this process takes several hours to complete.
We are working on that now and when the machine is back online we will work on restoring our backups for you.
