ADSL2 reliability

[NoMorePatience]

I have ADSL2 that stops working about every other month. The technician comes and checks lines within the house: no problems, all Ok. Then they leave and do something at the pillar and the internet starts working. Are they pulling and reassigning copper wires the way the used to when fixing phone outages? Ie Take a line that is not being used much and giving it to the customer with the outage.

Either that or a simple retermination at the pillar.
