What type of outage occurs when all locations experience a failure simultaneously?

A global outage occurs when all locations experience a failure simultaneously. This type of outage typically indicates a critical issue that affects the entire system or service across all geographical areas. It can be due to widespread problems such as significant hardware failures, software bugs, or network disruptions that impact every user and prevent access from any part of the world.

In contrast, a local outage would only affect a specific geographical area or region, thus leaving other locations operational. A performance threshold violation refers to instances where performance metrics fall below acceptable levels, rather than a complete failure of service. A partial outage suggests that some components or locations are operational, while others are not, which would not encapsulate the scenario of a total failure experienced uniformly across the board.
