Hi,

Today we made some changes to the production system, but did not anticipate
this having any effect on application's running with App Engine.  The
solution for Gary's issue is the one he suggested, but Joseph, I was
wondering if you could elaborate more on the scenario you are experiencing?

Also, please know that we are working to reduce the impact that such changes
will have on applications, and thanks for all your patience while we look in
to the issues here.
