## Updates from GitBook
### 2026-11-02 20:26 UTC: identified
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.

### 2026-11-03 03:37 UTC: monitoring
The incident has now been mitigated and all published content, editing, and Git services are back up. We are continuing to monitor and will post a detailed post-mortem in the next 24 hours.

### 2026-11-03 03:40 UTC: monitoring
Both app and public content components are operational.

### 2026-11-03 04:52 UTC: resolved
This incident should be fully resolved.
