Maintenance
Use maintenance windows to suppress alerts during planned work and show "in maintenance" on status pages.
Maintenance
Maintenance windows let you plan work (deployments, updates, migrations) without triggering noisy alerts. During an active window the affected target is treated as in maintenance — alerts are suppressed and, if the customer has a status page, the service is shown as Maintenance instead of Degraded.
Create a maintenance window
Go to Dashboard → Maintenance and create a new window.
| Setting | Description |
|---|---|
| Target | Exactly one: a website, a service monitor (ICMP / SMTP / SSH / FTP / IMAP-POP), or a DNS monitor. |
| Name | A friendly label, e.g. "Weekly updates". |
| Description | Optional notes shown in history. |
| Start / End | The window's time range. Times are interpreted in your timezone. |
| Active | Toggle to enable/disable the window without deleting it. |
One-time vs recurring
A window is either one-time (default) or recurring. Recurring windows carry a recurrence pattern:
| Field | Meaning |
|---|---|
frequency | daily, weekly, or monthly |
interval | Repeat every N days/weeks/months (e.g. 2 = every other week) |
daysOfWeek | For weekly: which days (0 = Sunday … 6 = Saturday) |
dayOfMonth | For monthly: day of month (1–31) |
endRecurrenceDate | Optional date when the recurrence stops |
The Start / End times define the window's length within each occurrence.
Effect on status pages
If the target's customer has a status page:
- A target with an active maintenance window (and no open incidents) is shown as Maintenance.
- Maintenance windows can also appear in Recent History (controlled by the status page's Show recent maintenance toggle — see Status Pages).
Maintenance does not override real outages: if there is an open incident during a maintenance window, the service is shown as Degraded, not Maintenance. See Incidents.
Troubleshooting
Window does not show as "active"
- Verify Active is enabled.
- Confirm the current time is between Start and End.
- Check the start/end times are correct for your timezone.
- For recurring windows, confirm today matches the recurrence pattern (
frequency,daysOfWeek/dayOfMonth) and is beforeendRecurrenceDate.
