I think in summer when the decline started ntl suddenly decided to do one of the 3 things to avoid their traffic bills going up when they rolled out 10mbit.

1 - Stop upgrading external pipes with traffic utilisation.
2 - Artifically throttle traffic to keep them below max capacity.
3 - Reroute traffic over cheaper routes which in turn has led to congestion because since summer they have been agressively using cogent.
