Sony Computer Entertainment has recently release this on PlayStation Europe Blog, and here we are passing news onto you.
Today our global network and security teams at Sony Network Entertainment and Sony Computer Entertainment began the final stages of internal testing of the new system, an important step towards restoring PlayStation Network and Qriocity services.
As previously mentioned, we’ve been working around the clock to rebuild the network and enhance protections of your personal data. It’s our top priority to ensure your data is safe when you begin using the services again.
We understand that many of you are eager to again enjoy the PlayStation Network and Qriocity entertainment services that you love, so we wanted you to be aware of this milestone and our progress. We will provide additional updates as soon as we can.
