## Timeline of updates

- **investigating** 2026-03-18 02:07 UTC: We are aware of an issue affecting experiment reporting data for a subset of accounts. Affected users may see incomplete data for some experiment iterations in the UI.
- **identified** 2026-03-18 02:08 UTC: The issue has been identified and a fix is being implemented.
- **identified** 2026-03-18 04:17 UTC: We have implemented a mitigation that restores data availability for all current experiment iterations. Affected accounts should now see up-to-date reporting and exposure data in the UI.                                                                                                                                                                                                                                         Our team continues to work on restoring data for previously affected experiment iterations.  We will provide a further update once full historical data recovery is complete.
- **identified** 2026-03-18 22:37 UTC: Our team continues to work on restoring data for previously affected experiment iterations.  We will provide a further update once full historical data recovery is complete.
- **identified** 2026-03-19 04:52 UTC: Our team continues to work on restoring data for previously affected experiment iterations.  Complete data restoration expected by tomorrow.
- **resolved** 2026-03-20 00:29 UTC: Our team completed the data restoration for previously affected experiment iterations.  Complete data is now available for all experiment iterations in the UI.
