The Free pricing tier doesn't have a associated Service Level *Agreement*, but has a Service Level *Objective* of 99.5%. Transient connectivity issues are observed if there was an upgrade, unhealthy underlay nodes, platform maintenance, or an application overwhelms the API Server with requests, etc. If your workload doesn't tolerate API Server restarts, then we suggest using the Standard tier with Uptime SLA.

The Uptime SLA feature in the Standard pricing tier enables a financially backed, higher SLA for your AKS clusters. Clusters in the Standard tier come with a greater amount of control plane resources and provide automatic scaling. The Uptime SLA feature guarantees 99.95% availability of the Kubernetes API server endpoint for clusters using [Availability Zones][availability-zones], and 99.9% of availability for clusters that aren't using Availability Zones. AKS uses main node replicas across update and fault domains to ensure the SLA requirements are met.

To scale AKS clusters beyond 1000 nodes, you need to request a node limit quota increase by raising a support ticket in the [Azure Portal][Azure Portal] up-to a maximum of 5000 nodes per cluster.
