AO3 Fan Fiction Site Goes Down for Up to Four Weeks After Security Incident
OTW says AO3’s user database does not appear to have been stolen, but urges all users to change their passwords after the October 29 security incident. The 18-million-work platform could return in a degraded state before the potential four-week outage ends.
Archive of Our Own (AO3), one of the internet’s largest fan fiction platforms, has temporarily shut down following a security incident, with administrators warning the outage could last up to four weeks. The site went offline on October 29, 2026, when an admin posted that it was “down for maintenance.”
Subsequent updates from the Organization for Transformative Works (OTW), the nonprofit that runs AO3, confirmed a “security incident” had occurred, though officials said they were “still in the early stages of response, determining its scope.” The organization stated it does not believe its user database was stolen but urged all users to change their passwords as a precaution. A partial restoration in a “degraded state” — with some features disabled — may arrive sooner than the four-week maximum.
Founded in 2007, AO3 hosts more than 18 million original works and serves 11 million users, according to a 2026 OTW press release. The platform has seen surging activity in recent years, including tens of thousands of new stories tied to the gay hockey romance series Heated Rivalry and its main characters, Shane Hollander and Ilya Rozanov.
The shutdown has prompted a visible reaction across social media. Users have been tagging government agencies in distressed posts, and some fans have compiled Google Docs — described as “survival guides” for the “AO3 apocalypse” — organizing links to downloaded stories by character pairings. At least one such document has struggled to load due to high traffic. Others noted that the outage coincides with the start of November, timing that drew widespread commentary online.
The OTW did not immediately respond to a request for comment. The disruption highlights the platform’s role in everyday digital culture, with fan fiction increasingly influencing mainstream publishing and serving as a source of material for streaming platforms seeking works to adapt.
