Do I feel stupid? Well... considering it took me the best part of a week to work out what I'd done, yes.
The last thing I did before I left for Brisbane was to unplug the TV, stereo and anything else that might conceiveably cause a fire, smoke, power surges or anything else even remotely nasty. The only things I left plugged in were the router, switch and file server.
I completely forgot that my ADSL modem actually runs off the same powerboard as do the TV and stereo, with the result that the very last thing I did before leaving home was to sabotage my only means of checking email for the next 3-4 weeks. Bugger it!
I can't even phone anyone and ask them to fix it, as I only have a spare key to the deadlock left with a mate - the screen door doesn't lock itself, so I've never needed to worry about getting locked out because of it. Buggrit!
It wouldn't be so bad, except that the web site that I've been building for the mob up here is sitting on my internal web server at home, and I can't get at the thing
