Don't know if it's still an issue, but we played around with EC2
a while back, and found out that they don't wipe the disk between
customers. They merely rebuild the filesystem. That meant we could
look at /dev/sda, and see data from previous users of the system.
Not a huge issue for us, as we don't have any data that would be
particularly meaningful for anyone else, but it could be a major
problem for others.
