Archive of Our Own could remain offline for up to four weeks following a security incident detected during routine maintenance on October 29, 2026. The nonprofit Organization for Transformative Works has not ruled out user database theft, prompting widespread concern among users.
The fan fiction repository Archive of Our Own went offline on October 29, 2026, catching millions of users by surprise. What started as routine overnight maintenance escalated into an extended outage.
The Organization for Transformative Works (OTW), which runs the platform, initially expected work to last roughly 12 hours. The status page announced maintenance at 07:13 Coordinated Universal Time (UTC) on 29 October. By 09:03 UTC, the team stated the procedures would take at least 12 hours. By 17:41 UTC, the anticipated timeline for service recovery grew to approximately two weeks, with the possibility of extending to four. The security disclosure followed at 01:27 UTC on 30 October after administrators found evidence of an incident.
Organization for Transformative Works Investigates Security Incident
Administrators pulled the site offline as a precaution. Earlier today, we detected evidence of a security incident on AO3,
the statement reads. The nonprofit added: We are still in the early stages of response to this security incident and determining its scope.
OTW verified that “no AO3 data has been deleted”, ensuring that community members’ “works, bookmarks and kudos are safe.” The site hosts creative works inspired by Harry Potter, Marvel Comics, and the K-pop boy band BTS.
While we currently don’t believe that the user database was stolen, we are also unable to rule it out. The AO3 database contains account information that may include your username, email address, IP address, and a hashed version of your password.

The platform uses hashing techniques to secure passwords, but this cannot fully protect weak or reused credentials from being cracked. OTW urged users to change their passwords immediately on any external websites where they used the same login information.
Users Coordinate Digital Survival Plans
Launched in 2008, AO3 hosts more than 18 million fanworks and maintains over 11 million registered users. News of a potential month-long shutdown sent the user base into an immediate panic.
Fandom communities began digital organization. Previously downloaded fanfiction remains available on readers’ own devices, IGN Southeast Asia said. Readers and authors began sharing downloaded story collections and links to saved works. While the Internet Archive’s Wayback Machine offers another route to older links, reading saved copies locally or through archives fails to register views, kudos, or comments for authors.
Administrators Outline Recovery Timeline
The Organization for Transformative Works stated that restoring the website could take between two and four weeks. Administrators noted a possibility of bringing the site back up earlier in a degraded state, which might mean a read-only interface with missing features. Even if limited access returns sooner, the organization warned that recovery efforts could force additional unexpected shutdowns.
The organization has not confirmed whether sensitive user data was successfully compromised or provided a definitive date for when full functionality will return.
