   Earlier today, DnA Online Testing was experiencing errors, including 504/503 and general slowness. Online Testing is now back online after reverting a scheduled maintenance update. Our Engineering teams are continuing to closely monitor the situation, and updates will be posted here as they become available. We apologize for any inconvenience this may have caused.

   We experienced an issue affecting the Online Testing application within DnA. During a period of increased demand, the service did not scale as expected, which resulted in degraded performance and a failure of the Online Testing application. Our engineering team identified that a recent configuration change unintentionally impacted the application’s ability to scale. Once identified, the change was promptly rolled back, and performance returned to normal. We are now implementing additional safeguards, including enhanced monitoring and alerting, to help prevent this type of issue in the future and to ensure faster detection and response should a similar scaling condition arise again. We apologize for the inconvenience this may have caused and appreciate your patience as we continue to improve the reliability and resilience of our systems.
