Because its apparent there has been a blank version of the page cached
in edge-cache.

Can you perhaps hardcode your domain to go though a different
edge-cache? (ie put the www. as a A record to a different IP at the
DNS level.)

There are apprently a few of them
http://just-ping.com/index.php?vh=ghs.google.com&c=&s=ping%21


... because you havent revealed your domain name, we can't help you
find an edge-cache that has a valid copy.


(alternativly put the domain though some other CDN. Ie bypass Google
Apps and the Google Edge Cache altogether. It can proxy your appspot
URL - which is working ok)
