We had some problems over the summer. Internet service would go out for the daytime hours and come back at night. Comcast had no real explanation as to why. It hasn't been a problem for months now, but Saturday morning our internet service and TV was out. I thought 'oh no, here we go again.' It turns out that a neighbor was having their driveway replaced and the workers cut the cable. We were all back up in about 3 hrs.
