Minor June 16, 2026 Degraded: CAST AI node provisioning issues on AKS with Kubernetes 1.36 3h 32m EU Node Autoscaler, Node Autoscaler
Started Jun 16, 2026, 11:14 AM UTC· resolved Jun 16, 2026, 02:47 PM UTC
- identified Jun 16, 2026, 11:14 AM UTC
CAST AI node provisioning fails on AKS clusters running Kubernetes 1.36.0 or above. This is caused by Azure removing support for Ubuntu 22.04 (the OS currently used by CAST AI for AKS worker nodes) on Kubernetes 1.36+. Impact: Clusters upgraded to Kubernetes 1.36 on AKS will be unable to provision new nodes via CAST AI. Workaround: Do not upgrade AKS control plane to Kubernetes 1.36 until further notice. Next update: We are working on Ubuntu 24.04 support / temporary workaround and will provide an update once a fix is available.
- monitoring Jun 16, 2026, 02:08 PM UTC
We have identified a workaround which allows nodes to continue provisioning normally for the affected clusters. Node functionality is not impacted. If you have already upgraded to 1.36 and are experiencing provisioning failures, please reach out to support and we will assist in applying the workaround. A permanent fix with Ubuntu 24.04 support is in progress. We will notify you once available.
- resolved Jun 16, 2026, 02:47 PM UTC
We have implemented a workaround and successfully remediated all affected clusters. Node provisioning is now functioning normally, and node functionality is not impacted. If you are running Kubernetes 1.36 and experience any node provisioning issues, please contact Support and we will be happy to assist. For any further questions, please reach out to Support or your Technical Account Manager.

- identified Jun 04, 2026, 12:17 PM UTC
We are investigating an issue affecting a small number of Azure AKS clusters where node provisioning can fail. Current impact: • New node provisioning ("Add Node") may fail on affected Azure AKS clusters. • Existing workloads and running nodes are not impacted. • We are working on a permanent fix and monitoring all AKS clusters for further occurrences. We will provide updates as more information becomes available.
- monitoring Jun 04, 2026, 04:47 PM UTC
We continue to investigate intermittent Azure AKS node provisioning failures affecting a limited number of clusters in select regions. A mitigation has been applied to all currently affected clusters, and no additional customer clusters have been observed experiencing the issue at this time. We have identified the cause and are actively testing additional fixes to ensure compatibility with recent changes introduced by Azure's node bootstrap process. Our team is closely monitoring for any new occurrences and will provide further updates as progress continues.
- monitoring Jun 04, 2026, 07:40 PM UTC
Azure AKS node provisioning is currently operating normally. We will continue monitoring closely.
- resolved Jun 05, 2026, 06:42 AM UTC
A fix has been deployed to restore compatibility with recent Azure AKS node bootstrap changes.
