It's been 2 full days now and I still can't sign into PSN. It let me sign in once a few hours ago but when I tried to start a game a message came up saying "An error has occured you have been signed out of Playstation Network". Serioulsy don't know how many times i've restarted everything, it's still giving me error 80710B23. I noticed my time on the PS3 was also off by an hour so I went to date and time settings and tried to set it via internet couldn't do that either, said "The the current date and time could not be obtained". Wth is going on?
From what the article says it sounds like it might be a poor or unstable connection.
