Identified
Since 2026-03-20 approximately 09:00 AM PT (16:00 UTC), the Experiment Flags Management API (/api/1/flags) has been returning incomplete results. Customers using the Flags Management API may see empty responses when listing feature flags, even though flags remain visible and functional in the Amplitude UI. The Experiments API (/api/1/experiments) is not affected.
Our team has identified the root cause and a fix has been deployed. We are monitoring the rollout to confirm the issue is fully resolved. No data has been lost, and flags continue to evaluate correctly for end users. No customer action is needed at this time.
We will provide the next update by 2026-03-20 12:00 PM PT (19:00 UTC).
Monitoring
We have verified the fix, and the management-api is now fully operational. We will remain in a period of active monitoring to ensure continued stability.
Resolved
This incident has been resolved.
