Well if you ever clicked the "about the server link" on the home page it says this on their overall design / direction of the server.

Quoting for those too lazy to click link ;p
"Project 1999 started development in 2008, and was released in October of 2009. The mission of the project is to create the classic feeling that many had during the early days of Everquest during those time periods, starting with Classic content and releasing the other expansions and content on a similar timeline that was experienced on Live. The server will stop at Velious, at which point many options will be considered, including possible custom content that will maintain the spirit of the game, and/or an additional new server starting over at Pre-Kunark.
Project 1999 Red is a PvP Server run with the same framework as the main server, with some modifications for a better Classic PvP Experience. The PvP Server started in Classic and will follow a similar but slightly escalated timeline."
