I remember hearing that the site isn't accurate because of this:
Quote:
Updates on Character Creation Restrictions can be found here.
During periods of high congestion, we may institute a temporary restriction on the creation of new characters.
This information will be updated at the following intervals:
4:00 a.m./ 8:00 a.m./ 1:00 p.m./ 6:00 p.m./ 11:00 p.m. (PDT)
The site only updates at intervals, but you can make a character at any time so long as there is a slot for you to make it in.
