Emergency maintenance for EU2

Summary

Emergency maintenance for EU2

# Service Disruption - The EU2 cluster was unavailable ## Root Cause Analysis ### Duration of the incident Discovered: Dec 15, 2025 20:00 – UTC Resolved: Dec 16, 2025 02:00 – UTC ### Customer impact During the incident window, customers hosted in the EU2 region experienced intermittent service degradation. This included slower system responsiveness, temporary inconsistencies in monitoring data, and brief periods where alerts may have been delayed or inaccurate. Most customers regained access as services were progressively restored, and complete stability was confirmed before the incident was closed. ### Cause The incident was caused by an elevated load in the EU2 service environment, resulting in an uneven workload distribution across backend resources. As the load increased, automated recovery mechanisms were unable to stabilize the environment fully, necessitating a controlled restart of the regional service to restore normal operations. ### Effect The imbalance led to reduced service performance and temporary unavailability for some customers until recovery actions were completed. Engineering teams were required to intervene to safely restart the affected region and validate service health before returning operations to normal. ### Future consideation\(s\) * Improve automated workload balancing to absorb regional load increases. * Strengthen early indicators for backend saturation to enable earlier intervention. * Refine operational procedures to further reduce recovery time in similar scenarios.
