Maintenance window : ウィキペディア英語版 | Maintenance window
In information technology and systems management, a maintenance window is a period of time designated in advance by the technical staff, during which preventive maintenance that could cause disruption of service may be performed. == High availability services == For a high-availability service, such as an Internet hosting service or Internet service provider, the purpose of stating a time period in advance is to allow clients of the service to prepare for possible disruption or prepare for any major changes to the functioning of the service. This type of disclosure is typically guaranteed as part of a service level agreement. High-availability maintenance windows are often planned for a time where activity is at its lowest so as to cause minimal disruption to customers, though which also require unusual work schedules for the employees. An Internet service provider, for example, may schedule a maintenance window for Sunday during the night hours.
