Service disruption refers to any event that interrupts the normal functioning of a service, making it unavailable to users. This can occur in various sectors, such as transportation, telecommunications, or utilities, and may be caused by factors like technical failures, natural disasters, or maintenance work. When a service disruption happens, it can lead to inconvenience for customers and may require organizations to communicate effectively about the issue. Companies often implement contingency plans to minimize the impact and restore services as quickly as possible, ensuring that users can return to normal operations with minimal delay.
