My otherwise excellent ISP Gradwell suffered a heart stopping (for me at least) outage today:

Our primary fileserver has failed, causing primarily an outage of out web and shell account services. We are working on recovering this machine as quickly as possible, and apologise for the inconvenience this will cause. We regret no ETA is currently available.

I was at work an unable to check the dates of my last backups, but its seems to be back and working now. The outage was reported at 8am and fixed by 10:30am so no harm done. I am however going to make sure I have everything backed up when I get home tonight!
