so far bt has been the fastest in my village, we're about 4 miles from the exchange (and 12 miles from gloucester) so i can't get the full 8 meg. this speed is very consistent. service has been quite good. only one bad day in 6 mo. but they were having some major problems, along with a lot of other isp's that day due to a cable problem. took them about 5-6 hrs to fix it. no problems locally, installation was scheduled, engr. arrived exactly on time, installed it in a few minutes and so far so good.
