Last two weeks every morning around 9/9.30h in my timezone (=around midnight Pacific Time) our app encounters a very high increase in latency. Can not find the reason because the load is very low. Despite the low load three instances are created, as shown in the graphs below (taken on june 14th), and requests seem to take up to almost 15000ms ?! I have to admit we are still running the deprecated Master/Slave datastore (because we are still doubtful about some HRD restraints). But still, the behaviour is inexplicable for us. Any help or suggestion is much appreciated.
