And the prize goes to...
Paston's main webserver and currently reasonably main mailserver (as well as primary DNS), went down this morning. The disks in the SCSI RAID array died (oops), and took the raid array out. John and Dave are now reinstalling all the packages after pulling the data backups from the USB disk (yay for backups!). Hopefully it'll all be up and running again RSN.
Today is not turning out to be a good day.
