If you're using Jekyll, why not just host with S3/Cloudfront?
- I wanted to use Sinatra to 301 old tumblr urls
- Call me weird but I loathe seeing *.html in urls and that's the only thing you can do with S3 root object (when I checked a few months ago)
- something I can't remember. maybe it was cf edge server time to update when altering updates.
You can configure name of index file, and that will be displayed for requests against root URL and subdirectories (such as blog posts) as well. No need for having .html in URLs.
The only problem I've encountered with S3 web hosting is that it does not let you host naked domains.
OK that was actually the answer.
