    Between 14:36 and 14:43 UTC, all GitBook documentation sites using a custom domain were returning a 404 "Not Found" error, making documentation unavailable to users. The issue was caused by a problem introduced by an upstream provider that affected our deployment. The incident was resolved by rolling back the deployment, after which all sites were confirmed to be fully operational.
