Uptime feature

I'm testing the uptime feature with two of my sites.
My feedback is that I'm getting too much E-mails "xxx is down". I guess that the reason is that I'm running the sites on Google App Engine where requests sometimes fail (or take long). If one single request fails, that's still ok (in my case).

So my wish would be: only report a failure and send an e-mail, if subsequent requests fail.

Best regards
