I remember someone say that you can make your own servers, and I plan on doing so soon. Maybe we could use this as the DB league server?
The DB isn't the right place to ask this sort of question.
If you want to know the answer then ask a Programmer on Showdown or Smogon.
I know that PanPaw is a Programmer so you might want to talk to him.
Just read This and everything should be cleared up.
A tutorial on how to host/make your own showdown server that was found from a smogon post.
This is a simpler video, but this one isn't official and won't show up on the official page, which means you have to invite by link. These servers also aren't 24/7.
