This, unfortunately, is not something that any hosting provider has control over. The in-game list does not display the totality of ARK servers which online. You can crosscheck the number of servers shown in your game client against what's available on server listing sites (which in themselves don't even show them all) and observe there will be quite a difference in server counts. It's been our experience that the servers shown in the list will be effectively random depending on the user. I don't speak for everyone, but I know many serious players will search server listing websites to find a new server as opposed to using the in-game browser.
