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.
