**GitBook Services Unavailable – Major Incident** A 16.5-hour major incident disrupted SSO-based login to the GitBook app and blocked access to published sites using authenticated access, while public sites remained unaffected. The issue prevented users from signing in and stopped visitors from loading content on authenticated sites. The incident was fully mitigated, with all published content, editing, and Git services restored and confirmed operational.
We’re currently investigating an issue affecting logging in to the GitBook app via SSO, as well as published sites that use authenticated access. Users may be unable to sign in, and visitors to authenticated sites may be unable to load content. Public sites are not affected and are loading as normal. Our team is actively working on a fix and we’ll share another update as soon as we have more information.
