You almost gave me a panic attack! But then I realized I've already booked 2012, so the system wouldn't let me double-up (phew!).
I logged in at 6:01am PST (figured I'd overslept and would be SOL), the system spun its 'loading' circle a few times, and just about when I was ready to attempt log-in on a 2nd computer the availability popped up. My confirmation email came through at 6:06am PST. Interestingly, the website never did load the confirmation (the circle kept spinning) but I figured the email confirmation meant I was good to go!
I wonder if someone's internet provider/speed plays into access issues at all??
