added a second paragraph:
Note: When the web pages move from one server to another, SSH will display a big,
scary warning about the encryption keys changed. SSH remembers information about a
host, and when you connect to the same machine and the information doesn't match, it
displays a warning to indicate that there may be a "man-in-the-middle"
security attack going on. When you see this, you should verify that the server
really did change and then update your "known_hosts" file (delete the now-obsolete line).
You can think of this as a way to notice when the server move has happened.
Obviously if the data moves from server to server often, this will become annoying,
making the technique less useful.
