PANiCnz:
Signed up to this deal with Skinny on 10/11. Got a confirmation email at 5:50pm confirming my switch over on 24/11. But at 5:48 on 10/11 my fixed IP with Bigpipe changed. I'm not too worried about losing the fixed IP as I made provisions to live without it on Skinny, but it does seem like too much of a coincidence. Have yet to notify Bigpipe I am leaving.
@PANiCnz You do not have to notify Bigpipe you are leaving
