This is what I see:
You have mapped the domain willfaulks.com to wwwdotwillfaulksdotcom.wordpress.com. That blog address was redirecting as "www.willfaulks.wordpress.com" so I updated the blog address to "willfaulks.wordpress.com."
It will take up to 72 hours (again) for the propagation of the domain mapping to correct to this updated address, so you may see an error screen in the meantime.
You should be able to log into your blog dashboard, and you can update your site title in Settings > General, if you like!
