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

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.

So there may have been gradual deterioration before the actual failure.
