Question:
Pick one IP from each region, find network latency from via the below code snippet
(ping 3 times), and finally sort the average latency by region.
http://ec2-reachability.amazonaws.com/

1. us-west-1 [50.18.56.1] - 100ms (Smallest average latency)
2. xx-xxxx-x [xx.xx.xx.xx] - 200ms
3. xx-xxxx-x [xx.xx.xx.xx] - 300ms
