Almost 24 hours after Sony restored the PlayStation Network and Qriocity in the U.S., Europe and the Middle East, there was no word on the restoration of the services in Japan and the rest of Asia.

It has been reported that Japanese regulatory watchdogs have not given the final go-ahead to Sony for the restoration of the services in the country on grounds of niggling doubts over network security.

Meanwhile, there have been reports that the PSN restoration in the U.S. and Europe was far from being a smooth affair, with occasional server glitches slowing down the process much to the disappointment of avid fans who skipped sleep to lay hands on favored games.

It was mainly a flood of password reset requests that slowed down the network. Sony acknowledged the glitches and requested users to be cooperative.

Due to the high volume of emails, some users are experiencing delays receiving their password reset instructions. Thanks for your patience, Sony said in its PlayStation Twitter account.

However, fans were miffed at the slowdown and other restoration glitches. Damn you #PSN! They're postponing again because of all the password updates theyre receiving, tweeted an angry user going by the name m_Rajon Rajon M. PSN struggling to deal with huge mass of password resets, said another user named 'gotjammed'.

In Japan, the authorities are still not convinced about Sony's assurances over preventive measures for warding off network breaches and the company's efforts to restore consumer confidence.

As of May 13, Sony was incomplete in exercising measures that they said they will do on the May 1 press conference, Kazushige Nobutani, the director of Japan's Media and Content Industry department at the Ministry of Economy, Trade and Industry said, according to the Australian.

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, Nobutani said.

Sony has assured ample security measures will be put in place to prevent a repeat of the massive data breach it suffered in the PlayStation network in April.

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, company wide commitment, the company said in a statement as it announced partial, phased restoration of the network in the U.S. and Europe.

It is hoped that Sony would be able to announce that PSN outage in Japan is over as they wind up talks with the Japanese authorities.

We are still in talks with various authorities (in Japan and Asia), spokeswoman Kumie Tanaka said. Sony has said it expects to complete the restoration process in all countries by May 31 and that it plans to work it out on a country-by-country basis.

The massive security breach came to light in April and fears spread that hackers might have got crucial information pertaining to credit card numbers, purchase history and password security details of millions of members.

The gaming giant revealed then that the hacking of 77 million PlayStation customer accounts happened between April 17 and 19. User data like names, addresses, user names, passwords were compromised. Later reports showed even credit card details of as many as 24.6 million customers having Sony Online Entertainment accounts were compromised.

Sony then went into damage control mode and pulled the plug on services like gaming and music streaming. The tech giant also apologized for one of the largest security breaches in history and offered damages to the affected users.
