Issues for some partners using Connect Javascript APIs

This incident has been resolved.

On September 29-30 2025, for about 24 hours, Confluence Cloud experienced an incident due to the unintended deprecation of ACJS methods (https://developer.atlassian.com/cloud/confluence/about-the-connect-javascript-api/#connect-javascript-api) linked to retired V1 APIs (https://developer.atlassian.com/cloud/confluence/rest/v1/), resulting in 410 errors affecting partners reliant on these APIs. This issue is resolved, we will be working on a longer-term solution to prevent a similar incident from occurring again.
