The domain can now be assigned to the newly created directory with the index page in it.
The configuration can be done via My Panel in the area «Hosting», after navigating to the sub-category "Settings". Click on the arrow-icon of your website, then under "Redirects" click on "Edit forwarding".
After the popup shows up, click on the newly created folder (e.g. "maintenance") in wich you uploaded your index.html file.
As soon as the popup is updated, you can hit "save".
