Can we have OOB maintenance information enabled?
Every month we have prod deployment to our sharepoint on premises environment and it require downtime of minimum 5 hrs(not because of sharepoint due to some other integration with Microsoft product).
And this downtime will be always surprise for end customer who are accessing the site(we can do some customization to handle to inform the end user upfront by showing message in the page), and this will be common scenario for all admin/dev team. Here I am suggesting sharepoint team to have one OOB feature which will help us to show the proposed down time for the end user by activating this). Zero down time is possible in sharepoint 2016 but when we have integration with some 3rd party component like Microsoft dynamics and if they are doing any maintenance activity then our web should not be available for end users.

According to the blog below, there is an OOB capability for this (SP2013)
Implement via PowerShell via a New-Object Microsoft.SharePoint.Administration.SPMaintenanceWindow
This is applied per content database

Its a very good idea. As most of us face this issue on a day to day basis during production deployment
