Blog*Spot is currently not serving when a domain is pre-pended with www. To clarify, www.subdomain.blogspot.com will not serve but subdomain.blogspot.com will. You can view your blogs by removing the www and we are working to restore access.
Update: This issue has been resolved. You may need to clear your browser's cache if you still cannot access your page at www.subdomain.blogspot.com.
