I tried The BT speedtest and it doesn't like my phone number. It needs a "service ID"
Did it just head this by "Test Error"? That means you are not on a BT system but on LLU. You have no "service ID"!
EDIT: Ah! It sounds like when you got those higher speeds you were on BT IPStream, then the "something at exchange" was to switch you to C&W LLU, as uno suggested. This must be very congested. Do you have lots of big Tescos in your area?
