High Quality Content by WIKIPEDIA articles! PlayStation Network, often abbreviated as PSN, is an online multiplayer gaming and digital media delivery service provided/run by Sony Computer Entertainment for use with the PlayStation 3, PlayStation Portable and PlayStation Vita video game consoles. On April 19, 2011 the PlayStation Network (and later also Sony Online Entertainment`s network) was put offline due to a "compromise of personal information as a result of an illegal intrusion". At the time of the intrusion, the network consisted of "approximately 130 servers, 50 software programs and 77 million registered accounts". On May 14, 2011, Sony began regionally restoring the PlayStation Network and released a mandatory security firmware update which requires users update their passwords. A new license agreement was subsequently introduced, legally barring users from filing lawsuits and joining class action lawsuits.
