Monitoring - As of 11:22 AM Eastern Time, the system that processes updates to segment membership for the purpose of building campaign audiences was restored to full performance. As of this time, we are no longer experiencing delays related to segment membership.

Apr 9, 11:27 EDT
Investigating - At around 9:10 AM Eastern Time on April 9, 2025, the system that processes updates to segment membership for the purpose of building campaign audiences began to experience delays. Currently, this system is delayed by up to 60 minutes.

As a result, campaigns with segment-based audiences may be impacted. For such campaigns, estimated recipient counts as well as actual recipient lists may be based on segmentation membership that is up to 60 minutes out-of-date.

Segment creation is not impacted by this delay. Creation of new segments and updating segment definitions are functioning as expected.

Flows triggered by segment membership are not impacted by this delay and are functioning as expected.

We have identified the issue and are working to restore the performance of the impacted system.
