smoke and mirrors system administration - noun phrase - When you bring a problem to your support team and they go silent for hours to days at a time. No amount of poking and prodding is sufficient to get anyone on the team to respond to your requests for status updates. When they finally get back to you they say that nothing's wrong and you must have made a mistake. Your thing is now unbroken. They never tell you (or anyone, for that matter) what they fixed or how they fixed it.
