I have been with Virgin since it was Telewest, BlueYonnder and Yorkshire Cable
All told about twenty years
It fails maybe once or twice a year and then only for a couple of hours.
Most failures are caused by Mains Power failures because I live in a village on the edge of town and the local SubStation keeps failing
340 down, 26 up, v6, tivo, phone. £50.00 beat that anyone?
