As the result of a criminal cyber attack on the company’s data-center located in San Diego, California, U.S.A., SNEI shut down the PlayStation Network and Qriocity services on April 20, in order for the company to undergo an investigation and make enhancements to the overall security of the network infrastructure. Implementing new and additional security measures, the company started a phased restoration of services in Japan on May 28. Further, after conducting testing of the payment process and commerce functions, the company restored services in Hong Kong on June 14 and in South Korea on June 24, following full restoration in the Americas, Europe/PAL territories and in some Asian countries and regions on June 2. With the full service restoration in Japan, PlayStation Network and Qriocity services will have been restored in all countries and regions where the services were operated before the system was shut down in April.
