Accidentally did /stop on a minecraft server?

I'm co owner on a minecraft server, and i was trying to do /stoplag but i pressed tab and enter too fast and accidentally did /stop which closed the server, i didn't know that command existed since i've never used it, is there a way to un-stop it?

Restart the server. How else would you do it? You haven't frozen your server in time, forever stuck in limbo. It just stopped.

So then the server is gone permanently? We have to restart and make a new one?
