Incident Report Summary On 25 September 2024 from 01:27 to 12:28 US/Pacific, Mandiant Security Validation SaaS customers were unable to run or create Actions, Sequences and Evaluations for a duration of 11 hours and 01 minute. Customers were able to login and view the UI and observe results of previously run jobs, but were unable to create and run content (Actions/Evaluations/Sequences).

To our Mandiant Security Validation SaaS customers whose business was impacted during this disruption, we sincerely apologize. This is not the level of quality and reliability we strive to offer you, and we are taking immediate steps to improve the platform’s performance and availability. Root Cause This issue occurred due to an implementation issue in a backend database that limited a sequence column value. The value was incremented beyond that limit causing the database and system to encounter an error which prevented users from running Actions, Sequence and Evaluations. Remediation and Prevention Google engineers were alerted to the outage via a support case on 25 September 2024 at 01:41 US/Pacific and immediately started an investigation. Once the nature and scope of the issue became clear, Google engineers adjusted the column value limit that was causing the issue. This required taking Mandiant Security Validation SaaS briefly offline to perform the necessary changes needed to resolve the issue and prevent it from recurring in the future. During this time users were redirected to a maintenance page informing them of the outage. Once the system was brought back online, engineers verified the underlying issue was resolved and that no further issues were encountered. Google is committed to preventing a repeat of this issue in the future and is completing a : Thorough review of the system settings to ensure no further limitations exist that would cause this or similar issues to occur.
