Incident Report

Summary AI Generated

Optimizely experienced data processing delays in the North America region lasting approximately 66.5 hours, which prevented continuous campaigns from running and caused recurring US campaigns to be temporarily paused as a precaution against duplicate sends. A fix was implemented on June 23rd, after which processing resumed and the backlog gradually cleared. The incident was fully resolved on June 25th, with all campaigns returning to normal operation.

We are currently experiencing data processing delays in the North America region. As a result, continuous campaigns will not run until the processing lag has cleared. Our team is actively investigating and working to restore normal processing times. We will provide an update as soon as we have more information. We apologize for any inconvenience and appreciate your patience.
