[Heuristic] Visibility of system status [Justification (From Nielsen)] The system should always keep users informed about what is going on, through appropriate feedback within reasonable time. [Yes but...] 
Maybe the user doesn't and shouldn't care. This heuristic assumes a user population actually cares about what is going on. Many user's could careless unless it's going to cause them a problem. You should have some basic trust built with your users and that trust may mean only informing them in the case of a problem, or handling the back end status problems yourself.
