From Europe to the Americas to, well, my house in Australia, users (mostly of older "Fat" consoles, those released before 2009’s "PS3 Slim") are complaining that upon booting their consoles up, they’re unable to sign into their accounts, check their trophies, use dynamic themes or access the PlayStation Network. That’s fine, Sony say there are PSN connection problems, and that they are "looking into it".
Problem is, the error does more than just prevent you from going online. It prevents you from playing certain games offline as well. The screen above is what I was greeted with when attempting to play Heavy Rain, and pressing out of it simply reboots the PS3, returning you to the main menu screen. It’s the same story for other games that feature dynamic trophy support.
Sony say "stay tuned" for updates on the problem. In turn, we’ll update if we hear anything more.
While theories abound that this has something to do with the calendar (some users are reporting their date/time settings have been reset), bear in mind Sony has redesigned its PlayStation website over the weekend, so it’s likely the result of some tinkering under the hood for the PlayStation Network.
Whichever it is, though, you have to wonder at the design process that turns a network outage into something stopping you from playing an offline, singleplayer title."
