With the announcement of the new Dyno pricing on Heroku I had some questions about the mechanics of the new free Dyno.
I was wondering if it was possible to schedule sleep time for a Dyno. This way I could make sure that my application is down while most of my users are sleeping.
No, this is not possible. Your app will automatically sleep when it doesn't get any requests for 30 minutes, and will be awaken if a request comes in.
If you have exceeded your daily quota, the app will just not be awaken.
