It would appear a faulty* ADSL filter on the master socket can knock

the same place totally unmolested for years is another matter.

Lightning nearby?

No recent lightening so far as I know. But thanks for the hint.

As according to some sources at least, apparently ADSL filters can be
very sensitive to spikes in the voltage coming down the telephone
line.

No they arent, they are entirely passive devices.

insulation can break down if the spike is big enough.

You dont get spikes that big on the phone line.

The BBC transmitter on the Isle of Lewis had a "spike" come into the
transmitter hall down the phone line and cause thousands of pounds worth of
damage. They really can be BIG

I had a 'spoke' so big it burned out the telephone line, half te
computer equipment connected to it and some of the carpets.

And blew a TV socket out of the wall.
