Restart went as planned yet servers didn't restart

So basically I have 3 servers, which restart an hour apart. Never had an issue until tongiht. SmoothRestart did everything... restarted, but no server actually went back up. So I started them all manually. After this I decided to test SmoothRestart to see what happened, and it worked like it should. I have zero way of knowing why any of the servers didnt restart before. Doesnt make any sense to me. Cant fix something if I dont know the cause D:

Strange for all to fail to start back up like that. Using Dedicated OVH server. Super strange situation 

Basiclly the plugin only shuts down the server it has no way of rebooting the server you would have to set a cron job to put the server back up say like 30 seconds after the plugin runs
