Source-derived summary

The 2011 PlayStation Network outage (sometimes referred to as the 2011 PSN Hack) was the result of an "external intrusion" on Sony's PlayStation Network and Qriocity services, in which personal details from approximately 77 million accounts were compromised and prevented users of PlayStation 3 and PlayStation Portable consoles from accessing the service. The attack occurred between April 17 and April 19, 2011, forcing Sony to deactivate the PlayStation Network servers on April 20. The outage lasted 24 days.

Government officials in various countries voiced concern over the theft and Sony's one-week delay before warning its users. The breach resulted in the exposure and vulnerability of personally identifiable information, including usernames, physical addresses, email addresses, dates of birth, passwords, and financial details such as credit card and debit card information.

Background

Sony had faced some firmware and hacking-related controversies leading up to the outage. In March 2010, Sony launched a firmware update for the PlayStation 3 which removed the ability to install third-party operating systems like Linux. This move sparked significant backlash from the modding community. George Hotz, also known as Geohot, managed to jailbreak the PS3 firmware on January 2, 2011, and began sharing the jailbreak online shortly afterward. In response, Sony sued Hotz on January 11, 2011, for his jailbreaking activities.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as 2011 outage of PlayStation Network caused by electronic attack. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q2573988. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2011 and 2010.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
