Comment 23 for bug 932088

I personally not sure what happens here, but:

Just opening http://us-east-1.ec2.archive.ubuntu.com.s3.amazonaws.com/ubuntu/dists/natty-updates/ in a browser leads to 403 XML. Ok, suppose it's limited to only EC2. From out EC2 machine:

ubuntu@ip-10-243-34-224:~$ wget http://us-east-1.ec2.archive.ubuntu.com.s3.amazonaws.com/ubuntu/dists/natty-updates/
--2012-04-06 15:36:06-- http://us-east-1.ec2.archive.ubuntu.com.s3.amazonaws.com/ubuntu/dists/natty-updates/
Resolving us-east-1.ec2.archive.ubuntu.com.s3.amazonaws.com... 72.21.214.160

HTTP request sent, awaiting response... 403 Forbidden
2012-04-06 15:36:06 ERROR 403: Forbidden.

But, any url of http://us-east-1.ec2.archive.ubuntu.com.s3.amazonaws.com/* leads to 403. So again, I'm not sure this is really a bug vs something we don't know how to use.
