After remaining down for more than three weeks, Sony Online Entertainment’s PlayStation Network (PSN) is once again available in parts of Europe and the US.

Sony suspended the PSN and Qriocity services on April 20, a day after discovering a massive data breach that left as many as 100 million PSN and Qriocity members users to personal information thefts. The Japanese company itself admitted that the hackers pilfered a significant amount of customers’ personal data, including names, addresses and credit card numbers.

Restored operations in parts of Europe and the US include online gaming, music downloads and chat service. The company said that the Asian members of the PSN and Qriocity would also be able to re-enjoy the service soon.

The restoration of the service requires users to change their passwords and update their PS3 games console with a new firmware. Users will be able to avail the facility of free enrollment in identity theft protection programs.

Patrick Seybold, Sony's senior director of corporate communications and social media, said that the process of restoration could take a little bit of more time to reach the remaining parts of the world.

Speaking on the topic, Seybold said, "Please note that these services will take a bit of time to be turned on and rolled out to the whole country.”

Sony has plans to restore complete operations of online services, including purchases of games, by the end of this month.
