On May 28, 2024, at 16:04 UTC, we started to receive errors indicating an issue in Anaplan Amazon Cloud Public — Australia. These errors related to a small number of customers unable to carry out imports, and one customer unable to open their model. Most customers were unaffected and experienced no loss of functionality.  

Our investigation identified that the errors related to a specific subservice, which had been subject to a change earlier that day. To resolve the issue, we rolled back that change and full service was restored by 17:35 UTC.   

To prevent the issue from reoccurring, we are working with affected customers to understand their customer journey and improve our post-deployment testing approach. Alongside this, we are carrying out incident response training to enable us to react more effectively when issues are detected.  

We sincerely apologize for the impact this has had on your business operations. We understand the disruption these issues can cause to your business and users, and we are continuously strengthening our systems and procedures to avoid similar issues from happening again.   

If you have any further questions or concerns, please contact Anaplan Support. Thank you for your patience during this situation and thank you for being an Anaplan customer.
