scheduled outage

Announced maintenance window

A scheduled outage is a planned period when a system, service, or facility is intentionally taken offline—typically for maintenance, upgrades, or repairs.

Unlike unexpected outages, scheduled ones are announced in advance: The scheduled outage will occur Sunday from 2-4 AM.

Common in utilities, IT infrastructure, and telecommunications.
