Trying to log in brings up the message "Site Maintenance Notice: The server is currently down for maintenance. We apologize for the inconvenience. Please try again later." We'll do our best to find out when a good time to try again will be, but in the meantime you're on your own. Perhaps you could get some laundry done, or find a new sandwich recipe.
Update: A Sony rep tells us that "this maintenance should be completed by 1pm Pacific."
