Amazon recently announced root domain support for S3 hosted websites in a short post on the official Amazon Web Services website . Here's the bulk of the announcement - you can review the walkthrough over at the original post .
We are excited to announce support for hosting static websites on Amazon S3 at the root domain. Visitors to your website can now easily and reliably access your site from their browser without specifying “www” in the web address (e.g. “example.com”). Many customers already host static websites on Amazon S3 that are accessible via a “www” subdomain (e.g. “www.example.com”). Previously, to support root domain access, you needed to run your own web server to proxy root domain requests from browsers to your website on S3. Running a web server to proxy requests introduces additional costs, operational burden, and another potential point of failure. Now, you can take advantage of S3’s high availability and durability for both “www” and root domain addresses.
