Just did a Google search for [google appspot], and the #2 result is a large cluster of Google support forum posts, the first of which is...
My appspot application is forward to Google site, why ?
Questions are all more or less asking about variations of the symptom described.
The poster on this thread is treating it as if it's a competitor hijacking...
user.appspot.com/mydomain.com ! Some google app outranking/replacing my site!

www mapping stopped working for App Engine
...Just letting you know that we're aware of an issue where the www mapping suddenly stopped working for App Engine.We're still trying to determine the root cause of this, but we have a workaround in the meantime:
1) Access the settings for the 'Web Pages' service and add a custom URL (anything besides www)
2) Go into the App Engine settings and delete the www.domain.com entry and then add it again. This should allow the app engine service to use www again .
If you have this issue and you have not been using App Engine (or if the instructions above don't work), please post your domain name as well as the target URL and we can investigate further.
I haven't explored all the threads in depth, but issue appears to be unresolved.
