that's not how's it's done. There is a process there which goes by each posted links (and shortens them in tweets) and checks if there anything there. so technically you can shutdown the instance, post a link (if it wasn't previously "banned"), wait a couple of hours and bring the instance up. But it would be probably checked some time later. But come on, just make a simple page with 304 redirect on any platform.
