Rori, I ran into this same problem earlier - where I paid for always on and couldn't drop the min idle instances below 3. The new pricing showed me paying for those extra instances that weren't doing anything.
Since my app is starting to get a steadier flow of traffic now, I disabled always-on feature and created a cron job to basically ping the app every couple minutes to make sure the app is still active and memcache is populated, etc. This allowed me to drop down to 1 min idle instance with no issues and am able to see a more realistic picture of the new pricing charges for my app. Jeff -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
