It would be a nice feature if an automated message was sent to the email on file for the server admin when the server goes down.
I currently run a PS4 server. I was out of town the other day when a patch came through. My server was down for most of the day.
Luckily one of the players sent me a message through PSN and I restarted the server from my phone.
Slightly off topic, a mobile app for GPortal would be awesome
