It looks like everything to do with character slots is currently frozen -- I have three unallocated slots, and have been unable to redeem them since the server came back up. I also purchased a few more today, and those haven't shown up, either. Attempting to redeem a slot goes through the usual dialogs, and the unallocated slot count goes down by one, but when I switch servers or log out and back in, the unallocated slot count is back up to where I started today.
Unfortunately, I have no available (unlocked) slots on either of my two main servers, so I can't make a Praetorian there today. I wound up creating one on a server I don't normally use, hoping I'll be able to free-transfer it tomorrow.
