I can access all those sites fine aswell Mr Breath. Its only sporadically that I get the problem. Last time I got it was 19:20 yesterday. Hasn't happened since.
The problem being it never lasts more than 5-10 minutes so by the time I ring up NTL to get a BB tech to do some diagnostics its working again. I suppose when I get the problem I could stick in a proxy so I can access here, post that its not currently working and some kind person here could try out the renfrew transparent proxies. Its too much hassle for someone to goto though and it would be unlikely even if someone was keen to help that they'd read it in time to try it out.
Incidently its definately the 62 proxy I had been using

Anyway, reckon its something I'll have to live with.
