EC2 or Not -- is your favorite site running on ec2?

Do you want to know if a website is running on EC2? Use this tool to figure it out quickly.

For the domain rellik007.bryxen4.hop.clickbank.net, I found the following IP addresses:

- - PTR points to

Some EC2 sites:

animoto.com
www.ec2ornot.com -- that's me!
feedblendr.com
www.mogulus.com
www.rightscale.com

Some surprising sites that aren't running EC2:

info.rightscale.com - apparently they only eat some of their own dogfood
www.amazonaws.com

BTW, if the site CNAME's their sites to the EC2 address, the IP address will show up as an internal address. This is because Amazon uses split dns for EC2 so they see the private addresses.
