We have successfully identified and mitigated a high-latency condition in our core storage infrastructure that temporarily impacted the responsiveness of the Kubernetes control plane. Our engineering team is currently executing a phased reconciliation and rollout process to gracefully restart the management instances and restore full functionality. Existing application workloads continue to run normally and remain unaffected.
