Recently, a report from Bloomberg stated that PSN and Qriocity services would be down until perhaps as late as May 31. Those reports are apparently erroneous, and Sony has no deadline they are working with right now.

Sony Computer Entertainment America spokesman Patrick Seybold said that the company is running a series of tests with outside parties to ensure PSN’s security. It is believed that some services could be restored in a rolling fashion as May continues.
