So the server is having a bit of problems with forests getting up, moving forward, and consuming everything on their march to consume Haelun'or.   Due to this unexpected invasion of trees we might be down overnight, although nothing is certain.   Fret not however, for many backups exist and you might experience only small rollback to earlier within the day. (if, perhaps, sometime tomorrow morning.)   EDIT: Kowaman - Expect a 12 hour rollback - server will be up sometime tonight.
