To schedule when changes are implemented to CIs, you can create blackout and
maintenance schedules.
Blackout schedules are periods of time where changes cannot be implemented. For
example, create a blackout schedule for code freezes at the end of the year.
Maintenance schedules restrict changes to being implemented inside a specific period
of time. For example, you can create a maintenance schedule implement changes only
on the weekend. Maintenance activity is represented by a span, which is displayed as
a horizontal bar on the timeline and can appear in any color. Spans for requested
changes that occur outside their allowed maintenance periods appear in red on the
timeline.
Both blackout and maintenance schedules are condition schedules.
