What would you recommend to display a "status" message on the home page?

What would you suggest for displaying something like the following that is updated manually by a non-technical administrator?

The message would be to users that the admin supports who just want to know when something is offline and when to expect service to be restored.

Would be on the home page that would be sparse except for this status message and a login panel. Is this were a "sticky post" or page comes in?

Thanks in advance.
