Looks like everyone in GAE either 

- <strike>gets unlimited rate-limit </strike>
- rate-limit engine checks for key + ip + top level domain (or some variation) of the referrer as described in linked post
- **GAE is no longer a viable platform for API apps**

NOTE: this issue is not limited to the current fire - anyone on a shared platform, e.g. standard shared webhosting, is vulnerable to this issue.
