Last Thursday BT lost quite a few phone lines around the country, including ours (no 50V, no dialling tone) but somehow the Fibre To The Cabinet broadband was still working.
I was able to report the fault on-line, and could see that BT thought the fault was at the exchange!
When the phone line was restored Saturday afternoon Hon. No.1 Daughter rang and told me about this superb website where she had watched all the local strikes out her window, AND on the PC screen, and heard the thunder about the same time the sound wave was shown arriving on the screen.
The link below is centred just West of London, as can be seen from the arguments following the web address. But as I write, I can pull out a bit and watch all the strikes over Germany.
