I believe the site is going through a update to DNS records. Hopefully to get us Activation Codes.
However I do not think the "Server" will be accessible until after March 3rd but I could be wrong as it seems the approval process is taking some time and the site is evolving.
From what I have gleaned from looking at the description of what Infinite Infinity is there will be a lot to study once we have access to it.
(My distraction right now is Horizon Zero Dawn)
