I think its pretty clear that its a routing issue, my proxy presumably takes a different route to Cogent than the Bageley proxy, hence Bageley stays good 24 hours, the Poplar route gets congested after about 4pm, this seems to be verified by other posts complaining about Cogent connections both here (
http://www.cableforum.co.uk/board/sh...084#post548084) and elsewhere.
It seems another of those occasions where NTL are neglecting to maintain their proxy servers properly
