They currently have a message on the home page explaining the hiatus:
The Official Star Wars Blog is now on temporary hiatus as the Lucas Online team continues to explore new directions for StarWars.com. New authors, new articles, and new points of view are in the works for the Blog that will cover the entire Star Wars experience. As with all changes undertaken on the website, we are closely examining feedback from past surveys and user actions on the site, and we want to hear from you. Feel free to let us know in the comments what you’d like to see the Official Star Wars Blog become.
So here is your chance if you visit this blog to speak up about what you want, what features you’d like to see added and more. There are some really good suggestions up on the blog comments already. What would you add?
