No server is permanently locked for such period of time - the New Character Creation status changes dynamically based on the amount of the players in the start up areas and at even most populated servers you should be able to get in no more than 4 to 6 hours. The best time is late night / early morning for the given area time. I was creating a bunch of new characters on my server (EU) last Friday - e.g. the day both Trial and Invite Friend promotions started - and while arrivng home late afternoon I was unable to get into game before 7 pm so I was fully aware that I will not be able to create the character right away and indeed after designing the first one Moogle was closed. I've stayed at the creation screen while playing on another machine and I've tried about every 60 - 90 minutes if I can get in. I was tired so I went to bed before midnight and wake up at 2:20 am and was able to submit first character and create another 2 as well at that time.
