I just moved my code from one machine to another, released it and suddenly it created an entry with a key of "576728208506880" so I re-released the exact same code from the original machine and created another field and this time the key created was "21134006"
Can anyone shed any light on why this might be?!
Thanks, J
It's perfectly normal. App Engine generates numeric IDs between 0 and 2^53, and scatters them out throughout the entire range:

You can hack around it a bit by using the legacy auto id policy in your settings.
