Hi Takashi, I waited with my response because I didn't want to jump to conclusions. Yes, I have been experimenting with some settings every now and then, limiting instances, playing with the pending sliders etc. But all it did was change how quickly instances were created or collected (while always increasing latency). It didn't change how the billed instances were calculated. Above is the chart of my applications' instances for the past month. (The editor didn't allow me to place it at the right location...) It's rather easy to spot when things changed. We used to get billed for roughly one instance on average. Yes, we did have more than one running, but it was (and is!) always one instances that handles 95% to 99% of the load. So it seemed only just that Google would only charge for the main instances. I never asked for an instance that just sits there, but I didn't mind it while it was free :) So now being charged for two or three instances, when only one is really doing anything, seems like a major change that should be documented. Okay, maybe it's just our application, but our pricing has increased steeply. I just posted another message about the frontend hour calculation. Both issues combined seem to have led to a pricing increase from $5 to $10 before, to now $30 to $50. Our request per second have increased moderately, we may have made some requests slower, we might have slightly different usage patterns. But I cannot see a reason for a price increase this steep. Any help or insight would be appreciated. Our app ID is small-improvements-hrd Kind regards, Per On Friday, April 27, 2012 7:02:26 AM UTC+2, Takashi Matsuo (Google) wrote: > > On Fri, Apr 27, 2012 at 10:16 AM, Per <per.fragem...@gmail.com> wrote: > > Hi team, > > > > previously, the scheduler used to spin up 3 instances for our > > application, only used 1 out of the 3, but at least we didn't have to > > pay for the unused instances.
