That seems pretty late, but thought I'd mention AM radio interference. There used to be a guy in the AT&T Midwest forum familiar with all kinds of radio, lighting and transformer issues affecting ADSL.
Also my line had a bad Scotchlok in the aerial terminal. Like clockwork on a windy, sunny winter day it would cut out when the sun hit the aerial terminal aka boot. No problem except in the winter.
