You gonna leave it that late in the day and risk it?
Fuck that id be chewing my fingers nails off worrying and I'd imagine a lot of these sites will crash with so much web traffic pilling onto their servers in a 2-3 hour window... Then the quality will be shit as more and more people drain the servers just like Justin TV used to.
There's one site that's 99% solid with powerful servers for members only but it's the same site that was attacked and froze during Mayweather v The Ghost. 😉
