Thanks for the quick reply - phew, at least its nothing I've done - that's a relief.
Ah well, I suppose we'll have to wait and keep everything crossed then - I see that the price increased already though...
Yes, I had my box swapped on a Bank Holiday Monday. When they rang to make the appointment last week I said "you do realise Monday is a Bank Holiday". The guy that arrived was in a rush, and that's an understatment - definitely a subby on £/per box done. He swapped my Pace box while simultaneously holding a phne call with his boss and like I said, just rushed off. No "set up" of the new box etc. save the TV channels and PIN number. When I said "what about the internet" he said "oh, just switch the PC on once the signal comes through and it'll work"......yeah right...

Luckily I'd encountered the MAC address screens before but I hate to think what some normal non-technically minded customers are going through just restoring their "it was OK before" connections. Tech support will be very busy tomorrow!
Thanks again. I think I'll run a speed test once every couple of days to check.....going to be paranoid now
