A network outage occurs when a computer network becomes unavailable or experiences significant disruptions, preventing users from accessing services or resources. This can happen due to various reasons, such as hardware failures, software bugs, or external factors like severe weather. During a network outage, devices like routers and switches may fail to communicate, leading to a loss of connectivity for users. Businesses and individuals rely on stable networks for activities like browsing the internet, sending emails, and using cloud services, making outages a significant concern for many.
