Some points to address:
1 - It is better to add servers in bulk than piecemeal them into the entry. (Ie adding 5-10 new servers / data center for characters at a time).
2 - The additional servers they are implementing 9/3-9/4 will include new servers for characters on each Data Center, and additional servers for Instances (Duty Finder).
3 - The EU HQ declined hosting the Datacenter, and therefore the NA branch got stuck handling double duty (EU and NA).
4 - You will be getting a free 7 days added after the servers are up.
