AO3 returns online after 17-day security incident outage

Archive of Our Own (AO3) returned online on November 15, 2026, following a shutdown that began on October 29. The site reopened at 08:28 UTC on Sunday, earlier than the upper end of OTW’s two-to-four-week recovery estimate.

The fanfiction platform was inaccessible for approximately 17 days after its operator, the Organization for Transformative Works (OTW), identified evidence of a security incident.
