I wrote about hardware change issue and a couple of related issues a while ago: http://www.rotanovs.com/cloud/amazon-ec2-failures/ http://www.rotanovs.com/cloud/amazon-ec2-failures/ Also, to clarify, hardware change occurs when you stop an instance (which frees it, so it can be taken by another customer), and then start a new one using the same EBS volumes.
