10. investigating Jan 09, 2026, 10:41 PM UTC

    We are seeing delays processing the AI Session event queue, which is causing sessions to not be displayed on the AI Controls UI. We have deployed a fix to improve the queue processing and are monitoring for effectiveness. We continue to investigate other mitigation paths.

11. investigating Jan 09, 2026, 11:44 PM UTC

    We have deployed an additional fix and are beginning to see recovery to the queue preventing AI Sessions from showing in the AI Controls UI. We are working on an estimate for when the queue will be fully processed, and will post another update once we have that information.

12. investigating Jan 09, 2026, 11:56 PM UTC

    We estimate the backlogged queue will take 3 hours to process. We will post another update once it is completed, or if anything changes with the recovery process.

13. investigating Jan 10, 2026, 02:33 AM UTC

    Our queue has cleared. The last 24 hours of agent session history should now be visible on the AI Controls UI. No data was lost due to this incident.

    This incident has been resolved. Thank you for your patience and understanding as we addressed this issue. A detailed root cause analysis will be shared as soon as it is available.
