Not sure specifically about server restarts (does BF3 not support it?). As far as I know there's a load of different admin tools used by different server providers, so there might be some difference between them. I can probably find out about that but in general I can't really talk about any details. They're trying to make competitive play a big part of BF4, they want to break into the esports scene properly. There's a dedicated Esports Producer, Daniel Matros, who used to be a community manager.
