I have an interrogation regarding Heroku's dynos.
As of now my app runs two 512MB dynos and I was pretty certain that this configuration, i.e. more than one dyno, ensured that the container's application was started and ready to serve clients.
However, I frequently notice that the dynos are not always started and it takes something like 8 seconds to load the app. See screen shot below. The host XXXX.herokuapp.com spends nearly 8 seconds in "waiting".
Has anyone else experienced such issues with Heroku? How can they be resolved?
