Using the TBB map for my postcode area the typical speeds around my location were no surprise i.e. approx 2Mbps or lower where the location was even further from the exchange.
Right now the oddity, I noted a while ago that TalkTalk were a LLU provider at the exchange and just recently there are some 'logged' speed measurements on the TBB map but the DL speed shown is way over what one would expect compared to the other ISPs. The difference in one instance on the map is that TalkTalk gives a DL of over 3.5Mbps but all the other 4 tests show < 2Mbps
Hence the question just how are TalkTalk able to get such speeds compared to BTW connected users??? Afteral I thought they would be using the same copper just different "kit" at the exchange?
TIA for the insight
