I got up at 5:00 am central time and the email was in my box. Everything worked flawlessly and started downloading within 5 minutes.
The connections seemed to be throttled back to around 5 Mbit per connection, but could keep 4 connections going at 4 Mbit fairly consistantly. Had it all downloaded within an hour, and had 2012 installed within 35 minutes.

I must have beat the rush.

BTW, if you have a 64 bit system, in preferences it will allow you to check embedded in the library settings. Don't do it, you'll get the dreaded "no flash" screen.
