I have a medium size community site http://www.v2ex.com/ running on App Engine, it's running well but today all my users just keep receiving this:

Is Google changing anything? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to [email protected].
