Hi stamp92 and thanks for the info.
I can confirm that the following three do indeed work with Ntl.
cache-edi.cableinet.co.uk
cache-wol.cableinet.co.uk
cache-bas.cableinet.co.uk
The only problem is they don't seem to work in Firefox

they work perfectly fine in IE, and seem to be a lot faster than Ntl's IMO.
But Firefox just shows a times out dialog box.
