I think thats what they are called....

I am finding some sites arent working on my browsers, both firefox and IE

I use www.surfola.com, but does anyone know of any programs/sites which do similar jobs?

Also, if any IT tech's out there know why my internet does this, could you explain?

cheers,

your ISP's DNS don't work right... not an issue with you or your pc.
I'm on Demon internet and i can't get on overclockers.co.uk
using Demon's own web cache and it works fine.

my mate told me about http://proxify.com/ try that?

here's a list of UK proxies u can put into your IE settings.

Using the www.proxify.com site, works a charm
