Find region from within an EC2 instance

Question

Is there a way to look up the region of an instance from within the instance?

I\'m looking for something similar to the method of finding the instance id.

If you're able to use the AWS Java SDK, there is now a method that will return the current region name (such as "us-east-1", "eu-west-1"):
