    The Kubernetes cluster hosting impacted services currently has issues due to two outstanding bugs, one in the Linux kernel and one in Longhorn. We will upgrade both of these today evening on all nodes, to prevent future issues. The plan is to not impact workload availability, but as this is a big upgrade, no promises can be made.
