This is an example of how you can set up a scheduled maintenance event. To set this up, create a new issue in your @upptime repository and add the label maintenance to it. Then, you can add details in the comments. Make sure you also add an HTML comment at the beginning of the issue, which looks like this:

<!--
start: 2021-02-24T13:00:00.220Z
end: 2021-02-24T14:00:00.220Z
expectedDown: google, hacker-news
-->
