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

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 don’t get spikes that big on the phone line.
