Not how I meant to spend the morning

So there I was, wearily chugging through some online chores -- paying bills, banking, that sort of thing -- when the internet dies.

I reboot the router. No joy.
I plug a laptop direct onto the cable. No joy, but at least it proves it isn't my router.
I ring my ISP. "Everyone else is working fine. It must be your router." "No it isn't because..." "Ah..."
On their suggestion, I reboot the wireless unit on the roof (this can be done remotely, you will be glad to hear). No joy. Again on their suggestion, I change the power supply to the wireless unit on the roof. (I do wonder what they would have suggested if they were talking to somebody who didn't have a configurable power-supply directly to hand...). No joy. I visually inspect the wireless unit with binoculars. No apparent damage. I trace the cable from the wireless unit into the house  as far as I can either visually or physically (not fun in the snow). No apparent damage.
"Ah. Not sure what to suggest. It must be a problem at your location. We can't come out until after Christmas."

And then 30 minutes later, it miraculously springs to life. Which suggests it was their end all along but they haven't rung to confess... Grrr. I want my morning back.

P.S. Thanks to everyone who made suggestions about ebook location! I shall not be short of reading matter... unless the Internet dies again.

DW invite codes

I have a couple of DW invite codes if anyone wants them, or knows anyone who does... If they're not wanted within a week, I'll put them up on the DW invite community.
