Blueyonder‘s postcode checker gives me this:-
Unfortunately blueyonder broadband Internet and Digital TV are not available in your area
Hmm. I’m sure it used to say, "not yet available in your area." A small but significant change; have they just given up? There’s something slightly perverse about a company called Telewest Broadband telling you they can’t sell you broadband in an area served by Telewest Broadband.
