I'm having the the same problem, Since 2-3 weeks my blacklist is full of 1000k entries, I don't see anything suspicious neither in the dashboard nor in the logs but Google Bot started reporting http error code 503 (Service unavailable) on my web pages
I really don't know how to deal with this, is there any Google representative that could give us some suggestion about this? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
