The first hop values to your dsldevice are oddly high, they should usually be 1ms or <1ms.
However, as they others are sensibly low it indicates nothing too bad happening; probably just a router that prioritized tracert packets very low.
The 14ms 2nd hop makes it difficult to be sure if you are on interleaving or not; I get nearly that and I am not interleaved.
Overall 14ms to bbc isn't too bad; the others are sometimes a bit higher than they should be, but not by that amount.
You didn't mention if you were on wireless; that could still be the issue.
Unfortunately no issues in the past doesn't assure the same in the future; as more people get connected to your cabinet there can be crosstalk issues that lower you speed. They are trialing experiments to get over that, but ...???
Recently moved from BT Infinity 2 to PlusNet. Very happy so far.
