As Eneko already said, this really sounds like a network problem - if your
hosts lose connectivity to each other they will reboot themselves, and it
sounds like this is what happened to you.
You are sure there has been no changes to your network around the time this
happened? Have you checked your switch config is still right (maybe it
reset?)
Maybe the switches have bugged out and need a reboot? check the logs on
them for errors.
