I was using GAE with Gapps on my domain, however it seems that ghs.google.com is unavailable in China.

How can I use GAE on my domain without Gapps?

Edit: A solution I'm considering is using something like a proxy. This way the firewall doesnt see google. By the way, my site is not banned because of its content, it can be acessed normally using appspot. The problem comes from google apps redirections.

Any ideas how I can setup something like this?
