AWS issues with 172.0.0.0/12

Hi Mehmet,

A traceroute would be particularly useful.

Have you tried accessing http://ec2-reachability.amazonaws.com/ to verify if the green icons load? If not, any particular region that's broken? Could you collect a traceroute towards some of the working and non-working IPs listed there?
