Intentional downtimeshould not ring like the real thing.
Every time you take a service down to deploy, the alerts reach everyone and trust in alerting erodes. A maintenance window announces that downtime in advance.

What happens, and what does not
Checks keep running
Monitors are not paused; data keeps arriving so you can see later what happened in that window.
No incident opens
Downtime inside the window does not create a new incident.
No alert goes out
And that suppression is recorded in the delivery history, so it is clear later why nothing was sent.
Announced on the status page
A scheduled window is shown to visitors of your public page in advance.
Flexible scope
Usually the whole system is not going down — only a part of it.
Every monitor
For work that touches the whole infrastructure.
Specific monitors
When only one service is being moved.
A group or tag
Everything tagged "payments", say, without picking them one by one.
Where this stops
No recurring windows
There is no "every Sunday night" rule; each window is defined once.
Cancellable
If the work finished early or never happened, cancel the window and normal behaviour returns.
From the Starter plan
Creating and editing maintenance windows is a Starter feature.
