PlayStation Network and Qriocity Relaunches Delayed

Sony says "additional comprehensive system checks and testing are still required" to restart service after last month's security breach.

Sony has pushed back its anticipated restart of PlayStation Network and Qriocity online services, saying in a new PlayStation blog post that "additional comprehensive system checks and testing are still required." It did not offer expectations as to when the services might be back online.

Sony had reported on April 30 that it expected some services to resume within a week. The new blog post explains: "We were unaware (on April 30) of the extent of the attack on Sony Online Entertainment servers, and we are taking this opportunity to conduct further testing of the incredibly complex system."

Sony's PlayStation Network and Qriocity have been down since April 20 after an unauthorized person hacked into the accounts of an estimated 77 million users, gaining access to names, addresses, passwords and possibly credit card information. Information from Sony Online Entertainment also was stolen, which could mean that an additional 24.6 million users might be affected by the breach.

Sony reported May 5 that it had started the process of restoring service through internal testing. "We're still working to confirm the security of the network infrastructure, as well as working with a variety of outside entities to confirm with them of the security of the system," the new blog post explains. "Our utmost priorities are the security of the network and ensuring your data is safe. We won't restore the services until we can test the system's strength in these respects."

Last week, Sony said that it believes it has identified how the data breach occurred but not who is responsible.
