Hmm... Not good. Google writes that setting minimum number of instances means keeping them in reserve so that cold starts will be unlikely unless there are exceptionally high load spikes. Sounds like a bug in GAE then if your application is set to minimum one instance and you still get many cold starts.
Plus to Google: Seems like my email address is sometimes published because I usually get zero spam mail in my Gmail account except when I have recently posted something in a Google Group like this. So spammers seem to be able to somehow get my email address by scraping information from Google Groups or via some subscription mechanism. Very bad indeed if true (with the disclaimer that maybe it's not Google that is leaking email addresses). On Wednesday, February 29, 2012 7:24:45 PM UTC+1, Mark Rathwell wrote: > > > Ok, interesting.
