Outages are stressful events. But what does stress actually mean, and what effects does it have on the people working to resolve an outage?
The term stress was first used by engineers in the context of stress and strain of different materials and was borrowed starting in the 1930s by social scientists studying the effects of physical and psychological stressors on humans. We can distinguish between two types of stress: absolute and relative. Seeing a hungry tiger approaching will elicit a stress reaction — the fight-or-flight response — in most or all of us. This evolutionary survival mechanism helps us react to such absolute stressors quickly and automatically. In contrast, a sudden need to speak in front of a large group of people will stress out many of us, but the effect of this relative stressor would be less universal than that of confronting a dangerous animal.
More specifically, there are four relative stressors that induce a measurable stress response by the body:

In 1908, the psychologists Robert ...
