On November 24, 2022 at approximately 04:00 UTC, some customers reported experiencing slow performance when using the Anaplan platform. We followed several lines of investigation and identified a failed subcomponent. The subcomponent was removed, and performance was restored at 05:55 UTC.
Further investigation identified that a hardware issue affecting the underlying infrastructure of one of our application components resulted in the subcomponent failure. To avoid a reoccurrence of this issue, we isolated the faulty hardware. We also identified improvements to increase the tolerance of our application layer to ensure a similar failure in the future will not impact performance. In addition, we enhanced our monitoring to provide heightened visibility on similar failures so these can be addressed prior to causing performance issues on the platform.
We deeply apologize for the impact this 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 in the future.
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.
