If you're not already aware we have released two additional servers; one for the EU region and one for the US region.
Please head to our blog post for more information.
This obviously leads to the question "well, how do I join the new shiny servers?" The only way to do this at the moment is to delete your current character and make a brand new one on the new servers (US-West and EU-East.) Please consider this carefully before doing so as we cannot restore deleted characters or transfer items/knowledge between them.
We do have plans for additional character slots in the future but the when and how of this has not been decided yet.
