Actually that was my fault. I had just switched off the redirect of allthingsdistributed.com to www.allthingsdistributed.com and as such you ended up at the old MT installation. That is now corrected.

You are correct; to map to an S3 bucket you need a CNAME. But DNS doesn't allow the apex to be a CNAME so you will need to redirect that. Route53 solves that for EC2 with the help of ELB. But there is no such solution for S3 (yet).

I am using the www subdomain as much as possible, so the redirect only happens if a visitor actually types in the apex name, in all other cases they will get where they need to be directly. But I agree that it would be better to solve this at a different level.

Launch and then iterate...
