Wonder if that answer includes Compute Engine. Doubt it.

It would be interesting to try using App Engine to simply proxy traffic. I don't know enough about it to even know if it's technically feasible. I imagine the downsides would be many but it could be useful as a temporary measure while you're getting attacked.

Some people already use App Engine as a free CDN (http://www.digitalistic.com/2008/06/09/10-easy-steps-to-use-...) , I imagine it would be totally possible to use it as a proxy.
