Sony pulled the PlayStation Network and Qriocity offline on Apr 20 after a major hacking attack by unknown hackers. The intrusion by the hackers led to a breach of personal data, including passwords and credit card details, on more than 100 million users.
"Please note that these services (PSN & Qriocity) will take a bit of time to be turned on and rolled out to the whole country. The process has begun and some states are being turned on now, so please be patient as we reach your city and state," Sony said in PlayStation blog.
As a measure to check future attacks, Sony rolled out a new PS3 system software update. Sony asked all PSN users to change their password once PlayStation Network is restored. The Tokyo based company said that the update (v3.61) is mandatory.
In a video message posted on PSN blog, Sony's Kazuo Hirai said, "I can't thank you enough for your patience and support during this time."
"We are taking aggressive action at all levels to address the concerns that were raised by this incident, and are making consumer data protection a full-time, companywide commitment," he added further.
