Re: 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?

Hey there

AT&T is using 172.0.0.0/12 block as public IP for customers in USA. AWS seems to be blocking this block, I can reach 
to many sites just fine but i can’t get to some sites hosted on AWS such as reolink.com

If someone from AWS is reading the list, please fix this issue
