Checking Ping times to EC2 Instances from around the world
Ping is a nice little network utility, and a great way to quickly check connectivity to your EC2 instances and get a feel for the latency by measuring the round trip times. This of course requires that the security group for your instances allow ICMP traffic. If you do have ICMP enabled, you can check ping times to your EC2 instance from 6 locations around the world - San Francisco, London, Sydney, Hong Kong, Moscow and New York, with a click from Ylastic. Here are the ping times to one of our c1.xlarge instances running in the US east region (N. Virginia).
You can even do this from your mobile - iPhone, Android or Blackberry6.
