    Start Time: 1:42 PM PDT, August 4, 2025 End Time: 7:45 PM PDT, August 4, 2025 We experienced a partial outage in the Experiment web application where users were temporarily unable to edit variants within experiments. The editing interface was unintentionally disabled, preventing any modifications to variant configurations. Impact: - Users were unable to make changes to existing variants. - Other functionality—including experiment creation, viewing, and reporting—remained fully operational. - No experiment data or configurations were lost. Resolution: - The issue was identified and a fix was deployed at 7:45 PM PDT on August 4, 2025. Variant editing functionality has now been fully restored. We appreciate your patience and apologize for the disruption.
