XNA Game Studio 3.0 is scheduled for release today. I'm not sure what extra features it will have versus the Beta I've been using, but now that it is in it's stable release version, you should take the time to upgrade! I'm sure once the site is back up, there will be download links available at the XNA creators club website.
So the site is back up with a 62.5mb download for XNA Game Studio 3. When I logged in, I had to edit my profile info again. There is also a survey that they want you to take about your involvement in making video games. Be aware though it is a lengthy survey.
