When we first brought Xanga 2.0 site up, Xanga sites like yours (that hadn't been migrated over) redirected back to the frontpage. That was pretty confusing (and scary!), so we changed things pretty quickly so that Xanga sites that hadn't migrated over showed the following page instead:

http://anouska-fernando.xanga.com/

Hope that helps! The short version of that page is that your blog posts have been archived... they are definitely saved and available for a free download! You can download them by signing in here:

Or alternatively, you can upgrade to Xanga 2.0 here if you'd like:
