Feature request from tiwarimukesh, posted on GitHub Apr 03, 2016
Can we have an option in Magento admin so that when a site is in maintenance mode customers should see a CMS page which can be easily customized in Magento admin.
So the site owners have a flexibility to show the customized page with custom messages to the customers.

@tiwarimukesh: This is already available as extension:
These should provide you an option similar to what you're asking for (I'm not affiliated with any of these).
In case you wonder how I found out about this, here is the link to Magento Connect for Magento 2 extensions.

@ktomk I know that extensions exist for this feature but I it can be a part of magento core.It will also be helpful.
If this request seems not a good, it can be closed by Magento team.

I'm sure PR's for this are welcome - at least to decide about that.
