PSN may be back in key terrories such as the UK and US, but authorities in Japan have blocked public access to the service until further security assurances can be given.
"We met with Sony on May 6th and 13th and basically we want two things from them," director of the Media and Content Industry department at the Ministry of Economy, Trade and Industry Kazushige Nobutani told Dow Jones Newswires.
"As of May 13th, Sony was incomplete in exercising measures that they said they will do on the May 1st press conference.
"There were similar cases in the past that were caused by other firms, and we are asking Sony whether their measures are good enough when compared to countermeasures taken in the past."
Aside from some brief downtime at around 9:00pm last night, PSN has been working well in the UK since early yesterday evening.
The PlayStation Store remains offline for the time being.
