On October 29, 2024, at 18:55 UTC, we received a customer report that they were unable to create models or revision tags. This issue affected Anaplan Amazon Cloud — Europe and Anaplan Google Cloud Public - Saudi Arabia.
During the initial investigation, we identified that the issue may have been triggered after a release. We observed a deviation in errors that had begun post-release. To mitigate the issue, we immediately rolled back the release and service was restored at 19:57 UTC.
Further investigation identified that the issue was a result of a duplicate record being created. To prevent a recurrence of this issue, we are adding constraints to ensure that this type of duplication doesn't occur. We are improving our testing procedures, specifically tailored to capture issues with revision tags. We are also implementing additional monitoring to be able to capture these types of deviations.
We sincerely apologize for the impact this has had on your business operations. We know these issues can cause trouble for your business and users. We are always improving our systems and procedures to prevent similar issues from happening again.
If you have any further questions or concerns, please contact Anaplan Customer Care. Thank you for your patience during this situation and thank you for being an Anaplan customer.
