nope I saw a tweet from killzone that said the sony techs "were onto it".
Also found out the PS4 hangs if after getting the message when you try to back out of it. So I use "test internet connection" to see if it has come back up, that can be run multiple times. It says:
You are signed out of PSN
CE-33992-6
Obtain IP address; Successful
Internet connection: Successful
PSN Sign-in: Failed
(then "back" works).
by the way the web page side »
us.playstation.com/ doesn't give an error, just listens to your username and password, then doesn't login.
