Then you must be logging in on the wrong times...
Xbox downtime is far less than PSN... + the Xbox has a better connection... The Playstation has a shocking networking coverage and either loses connection or just goes down for a good few minutes or an hour FREQUENTLY.
I own both consoles + i own a PS4 and a Xbox One.
Don't start saying it's my internet connection... because I am on a 5G router which is Ethernet connected to all my consoles http://i.imgur.com/Gsxlqzx.png
I think in my life I have sent around 5+ messages to sony about their connection and stuff and to microsoft not so many.
To say I'm a Game Programmer, my job requires the use of the consoles to make sure that the Network Engineers have made the game working stable online... and most of the time playstation fails more than xbox.
Fair enough about your point with regards to the Xbox attack... but sony have been attacked far more times than Microsoft.
