Maintenance windows
Schedule one-time or recurring maintenance windows to suppress alerts during planned downtime.
Maintenance windows suppress alerts during planned downtime. They support one-time and recurring schedules.
How it works
During a maintenance window, all checks still run but alerts are suppressed. Failures during maintenance are recorded in history but do not open incidents or send notifications. The status page shows a maintenance banner.
Create a maintenance window
- Go to Maintenance in the sidebar.
- Click New Maintenance Window.
- Enter a name, select the affected monitors, and set the schedule.
- Save.
Schedule types
| Type | Description |
|---|---|
| One-time | A single window with a specific start and end time |
| Daily | Repeats every day at the same time (e.g. 02:00–03:00 UTC nightly) |
| Weekly | Repeats on specific days (e.g. every Sunday 01:00–06:00 UTC) |
| Monthly | Repeats on a specific day of the month (e.g. the 15th). For a day that some months lack (e.g. the 31st), it clamps to the last day of that month. |
All times are stored and displayed in UTC. Convert to your local timezone before scheduling.
If a monitor is still failing when a maintenance window ends, you will receive an alert on the next check (within ~60 seconds). This ensures a real outage that started during maintenance is not left unnoticed.
FAQ
Are incidents created during maintenance? No. Failures during active windows are recorded but no incident is opened and no alert is sent.
Does the uptime calculation include maintenance? Maintenance downtime is excluded from uptime-percentage calculations by default.
Can I cancel a maintenance window mid-run? Yes. Open the window in the Maintenance list and click End Now. For a one-time window this ends the active window immediately. For a recurring window this cancels the running occurrence and stops future occurrences; delete and recreate the schedule if you want it to continue.
