Platform Alerts — **Introduction** Between 14:25 UTC and 15:05 UTC on October 16, 2026, users were unable to log in to the platform or access their models. This disruption lasted for 40 minutes, affecting customers in the following locations: * us1: Data Center - US East * us2: Data Center - US West * eu1: Data Center - Netherlands * eu2: Data Center - Germany * eu4: Cloud - Europe * us5: Cloud - US East * us7: Cloud - US * ap1: Cloud - Japan **Root Cause** The incident was triggered when an administrative search for user roles initiated a resource-heavy query. This request occurred after selecting an empty role hyperlink, which started an extensive data synchronization process that didn’t successfully filter duplicate records. As a result of processing these duplicate records, our authentication system experienced extremely high utilization. This exhausted available resources and caused platform access services to become unresponsive. **Recovery** Our engineering team identified the issue and took immediate action. We temporarily scaled down the authentication service to reduce load, allowing the system to recover, and increased processing capacity. Once the authentication system stabilized, services were restored to full capacity. Additionally, we implemented operational guidelines for our Support teams to avoid triggering the resource-heavy search option while permanent fixes were prepared. By 15:05 UTC, the issue was fully resolved. **Corrective & Preventative Actions** We are implementing the following actions to prevent recurrence: * We have updated the administrative interface to display empty roles as plain text, preventing the resource-heavy query from being triggered. * We are optimizing the system’s query logic to deduplicate user records efficiently during synchronization processes. * We are automating user update synchronizations in the background to prevent these processes from impacting active user sessions. * We are increasing processing capacity and configuration replicas across all regions globally to enhance overall system resilience.
