We are currently investigating an issue affecting persistent volume management (PVC) and node provisioning within Managed Kubernetes clusters. As a result, some workloads may experience prolonged timeouts during volume attachment (AttachVolume timeouts) or delays in NodePool scaling and maintenance operations. Our engineering team is actively working to resolve the issue as quickly as possible. We will provide regular updates as new information becomes available.
