It’s your provider. Let me guess… Clanforge?
If so, they have a policy of waiting 2-3 hours so make sure the update does not cause problems before they apply it. It is the most stupid policy I ever seen because there never was a patch rollback as far as I know and since most players are running auto-update on the client and it’s impossible to revert back to an order version, it means that this “2-3 hours of waiting just to make sure we don’t have issues” causes exactly the opposite: 2-3 hours of nobody being able to connect, insuring that most if not all your players HAVE issues.
When the update hits on my gameserver account, its available within a matter of minutes, so is Oxide and RustIO, all ready to install. There is no delay, the client, server, oxide and map plugin are all ready within a very short time.
