Etymology
Origin of outage
Explanation
An outage is a sudden interruption in a service. An internet outage means you'll have to wait to watch your favorite show online. You may experience a power outage during a hurricane or snowstorm, when you can’t flip on the lights or use the microwave until crews repair the electrical lines. A computer network or server outage can have many causes (sometimes these are scheduled breaks in service, allowing maintenance to be done). Outages can be annoying and inconvenient, or even dangerous. The American coinage outage, first used in 1903, was modeled on shortage.
