Psn down

Was playing Wolfenstien when I was abruptly stopped and told by the game and system , that I was signed out. Logged out and back in fixed it. I'm posting from PS4 and don't know how to quote but NO NETWORK is perfect. I don't play on my laptop much but every 2 or 3 gaming sessions on Steam a outage occurs where I can't login to steam thus killing any chance of playing any of my Steam games._
