I usually watch on mmashare, their website right now says that they will have 5 streams ready to go once the PPV starts. The last UFC stream they had was incredible and HD, but the one before that was absolute poop.
The channelsurfing.net page is definitely gone. It's worth going to the website just to see the BIG ASS notification by the FBI. Sucks though, I watch most of my sports streams through them.
