It has always been and continues to be about load balancing. All of this data is hosted on clustered servers. Basically, they are trying to keep things spread out as best as they can for stability and such. You can go all the way back to Beta4 and pre-launch and find notices about it:

Procedures during Periods of High Congestion (Aug. 21)
We are expecting major congestion during the period starting with the Early Access on Aug. 24, 2013 at 2:00 a.m. (PDT) leading up to the official game launch on Aug. 27, 2013 (PDT).

If a large volume of players attempt to login to the game simultaneously, certain players may receive the following message: “This World is currently full. Players in queue: ##.” If you receive this message, we ask that you please wait until your login is processed.

In addition, in order to avoid server congestion related issues from multiple characters concentrating in the starting areas, we may implement restrictions on logins and/or the creation of new characters for a period of time after the servers open to the public.

We apologize in advance for any inconvenience this may cause and thank you for your understanding.
