I have a daily problem getting Intel.com, have to switch proxies to get there.
This is with the swansea proxies, nthell says i'm on cache 5, i usually switch to cache 7 to solve problem.
This has been occurring every day for some months now.
Also get intermittent connection problems with thisissouthwales.com, adobe.co.uk,
www.digitv-forum.co.uk. all solved by switching proxies.
