Update timeline

1. investigating Nov 17, 2025, 11:12 PM UTC

   We have seen indication of a potential high severity issue with the Zeta Marketing Platform. We are actively working to identify the issue (impact and cause) and will update you with findings and confirmation of affected services once collected. Additional communications will be sent periodically with updates while we move through identification, impact analysis, and recovery. We value your trust and apologize for any inconvenience.

2. investigating Nov 18, 2025, 12:35 AM UTC

   We are currently observing slower-than-usual performance in our user interface, specifically within the Events tab in Experiences. All underlying event processing systems remain fully operational, and no data loss or processing delays have been detected. This issue is limited to the UI and may cause updates or metrics in the Events tab to appear with a temporary delay. The related API, https://docs.zetaglobal.com/reference/get-recent-events-for-a-person, is also impacted and may experience slower response times. Our engineering teams are actively working to restore normal performance, and we expect resolution within the next few hours. Thank you for your patience as we complete this work.
