Intermittent access to custom app domain app in China by App Engine

It's weird here. We have the Google App Engine (GAE) application and the custom domain http://www.tradeos.com CNAME at ghs.google.com. In China, we regularly do not receive any response from the server for 20 minutes or so, then it works fine for some time, sometimes for several hours.

Other non-Chinese sites, such as CNN, operate continuously, so this is not a common problem with the reduction of the international Internet. From other countries we see no problems.

By the way, the non-standard Google domains x.appspot.com do not seem to be accessible, apparently blocked by the Great Firewall.

Any ideas? Thank!

It looks like it is a large firewall (GFW) in China. The Google App Engine supports IP switching, and some of them are blocked in China. We temporarily used CloudFlare, although we have other problems, such as random 502 errors.

You konw GFW and Google CNAME are blocked in China. You can switch CNAME IP or use reverse proxy.

You can use reverse proxy to get around this problem. Do you have access to the server with apache or nginx? If so, you can configure this as a reverse proxy. Otherwise, there are several SAAS that will cancel the proxy for you.
