On February 10,2015 we will be resetting dimensions!! The list includes the End, Nether, and Deep Dark. It was decided that we would hold off on resetting the Twilight Forest for now, but it will likely be done sometime in the future to reset the bosses and dungeons.
The Spirit World, Mystcraft Ages and Spatial IO storage cells will never be reset unless they become corrupted or cause problems for the server. We will be implementing a world border on the Spirit World, Nether, and Deep Dark to ensure there isn't too much of a strain on the server.
As with the overworld world border, it is a soft border, and can be upped in the event that the server needs more space.
