- postmortem Oct 24, 2025, 10:25 AM UTC
On October 15, 2025, starting at 10:53 UTC, Anaplan experienced a major service disruption. The incident began with a period of complete service unavailability for a subset of Anaplan regions, followed by a period of degradation as our teams worked to restore full functionality. The table below details the impact for each region. During the degradation period, the platform was available, but some services, such as CloudWorks™ integrations, processed at a slower rate than usual. **Region:** US1 – Data Center \(US East\) **Unavailability \(UTC\):** 10:53 – 15:18 **Degradation \(UTC\):** 15:18 – 15:34 **Region:** US2 – Data Center \(US West\) **Unavailability \(UTC\):** 10:53 – 15:18 **Degradation \(UTC\):** 15:18 – 15:34 **Region:** EU1 – Data Center \(Netherlands\) **Unavailability \(UTC\):** 10:53 – 15:18 **Degradation \(UTC\):** 15:18 – 15:34 **Region:** EU2 – Data Center \(Germany\) **Unavailability \(UTC\):** 10:53 – 15:18 **Degradation \(UTC\):** 15:18 – 15:34 **Region:** AP1 – Cloud \(Japan\) **Unavailability \(UTC\):** 10:53 – 14:41 **Degradation \(UTC\):** 14:41 – 15:34 **Region:** EU4 – Cloud \(Europe\) **Unavailability \(UTC\):** 10:53 – 14:41 **Degradation \(UTC\):** 14:41 – 15:34 **Region:** US5 – Cloud \(US East\) **Unavailability \(UTC\):** 10:53 – 15:01 **Degradation \(UTC\):** 15:01 – 15:34 **Region:** US7 – Cloud \(US\) **Unavailability \(UTC\):** 10:53 – 15:18 **Degradation \(UTC\):** 15:18 – 15:34 **Root Cause** The incident was triggered by a utility power failure at a data center facility operated by one of our infrastructure providers. This facility hosts a hub providing critical, shared services that our regional spokes depend on. Our data centers are designed with multiple layers of power redundancy, including Uninterruptible Power Supplies \(UPS\) and on-site backup generators. During this incident, our provider's backup power system failed to operate as designed. A malfunction in their power transfer equipment prevented the generators from taking on the electrical load. **Our Response** Our foremost commitment is to the integrity of our customers' data. Upon detecting the power failure, our global engineering teams and the partner responded immediately. Faced with the choice between a longer recovery with potential data loss \(by invoking our Disaster Recovery plan\) against a faster, direct restoration of the physically intact facility, we chose the path that guaranteed data protection and minimized the overall recovery time. **Recovery Timeline** Once power was stabilized at 13:08 UTC, we initiated a systematic, multi-phased recovery to safely restore services and ensure data integrity. All core functionality was restored by 15:34 UTC. Customers using CloudWorks would have continued to experience a level of degradation on these integrations as the service processed a large backlog of tasks. By 17:41 UTC, all platform services were stable, and the integration backlog was fully cleared. **Corrective and Preventative Actions** We are taking immediate and long-term actions to prevent a recurrence and strengthen the resilience of our platform. * **Immediate provider and facility actions:** In partnership with our infrastructure provider, we have completed a rigorous root cause analysis. Our provider has replaced the faulty equipment and audited their facility. We are conducting our own independent verification of these corrective actions. We are also deploying enhanced monitoring to provide earlier warnings of potential power-related issues at any of our provider facilities. * **Anaplan led resilience program:** This incident has highlighted a key architectural dependency. To address this, we are accelerating our long-term strategy to re-architect our platform for greater resilience. This program will reduce dependencies on any single facility and is designed to prevent a localized issue from having a cascading impact. Furthermore, we have initiated a comprehensive audit of power failover mechanisms across all our data centers to identify and mitigate similar risks. We apologize for any impact this issue may have had on your business operations. We are continuously strengthening our systems and procedures to ensure we avoid future disruptions to your business and users.
