GAE site has stopped working on a custom domain

Question

We developed a website that came a few days ago, but suddenly it stopped working on a custom domain. It still works fine on the appspot subdomain. I double-checked all the settings, they are all in accordance with the recommendations of gae ...

• http://www.thesudokutimes.com/ (this file does not work)
• http://thesudokutimes.appspot.com/ (available here)

Can anyone suggest what might be the problem?

Answer 1

This is not like the Google App Engine, but a more general DNS problem.
Using the Dnsstuff tools, you can see that your domain name was renewed by the registrar on November 23, 2010 and the IP for thesudokutimes.com cannot be determined.

I suggest you double-check your configurations and contact your registrar for support.
