Event processing delays

Update timeline

1. investigating Sep 24, 2026, 12:23 AM UTC

   We are seeing a delay in event processing that is impacting sub systems within the Zeta Marketing Platform. We are actively working to identify the root cause and will update once we have more information. Additional communications will be sent periodically with updates while we move through identification, impact analysis, and recovery

2. identified Sep 24, 2026, 01:03 AM UTC

   Users have been experiencing delays in event processing within the Zeta Marketing Platform, which may impact dependent platform features that rely on timely event handling. We have identified the root cause as a failure in our event-processing consumers that stopped new events from being processed in a timely manner. A mitigation has been applied, and processing has resumed. Event backlog is now decreasing. Based on current recovery rates, we expect processing to return to normal within approximately the next 1–2 hours (by roughly 11:00 PM EDT / 03:00 UTC). The next update will be provided by 10:00 PM EDT / 02:00 UTC, or sooner if recovery completes earlier. We apologize for any inconvenience and appreciate your patience.

3. monitoring Sep 24, 2026, 02:14 AM UTC

   Users have been experiencing delays in event processing within the Zeta Marketing Platform, which may impact dependent platform features that rely on timely event handling. We identified the root cause as a failure in our event-processing consumers and applied a mitigation. Processing has resumed, and the majority of the backlog has been cleared. A subset of event processing is still catching up and remains delayed. We are continuing to monitor recovery closely and expect processing to return to fully normal shortly. The next update will be provided by 11:00 PM EDT / 03:00 UTC, or sooner if recovery completes earlier. We apologize for any inconvenience and appreciate your patience.

4. resolved Sep 24, 2026, 03:00 AM UTC

   RESOLVED: The issue has been fully resolved. The Zeta Marketing Platform is now fully accessible for all users. We are closely monitoring for any further issues. Thank you for your patience throughout this incident.
