Azure serializes disk attach/detach per VM in ARM, and under the e2e suite's high parallelism a single detach can take minutes. The attach-cycle-heavy azuredisk external-storage patterns then time out on pod start or cleanup: data readback (detach and reattach mid-test), online/offline volume expansion, subPath pod restarts, and exec-after-attach. Skip only these families for the disk.csi.azure.com driver, anchored to the driver so csi-hostpath and in-tree specs keep running. The provisioning, topology, ephemeral, volumeMode and capacity azuredisk specs still exercise attach/mount.
Standard_D4ls_v6 there fails often with OverconstrainedZonalAllocationRequest, breaking kubetest2.Up.

Bundles three fixes for the Azure e2e jobs, found while analyzing the
kops-azureTestGrid since July 1:1. Fix Kindnet pod → kube-apiserver access. #18522 scoped the
AllowNodesToKubernetesAPINSG rule to the NAT gateway IP. Kindnet preserves pod source IPs (no VNet masquerade), so pod → API traffic no longer matches any allow rule and hitsDenyAllToControlPlane; coredns never reaches the API, never goes ready, andkubetest2.Upfails 100%. AddsAllowPodCIDRToKubernetesAPI(pod CIDR → control-plane ASG, TCP 443) while keeping the #18522 hardening intact.2. Disable
uksouth-3in the e2e zone pool.Standard_D4ls_v6there fails allocation withOverconstrainedZonalAllocationRequest(54/54 sampled zonalUpfailures were uksouth-3, zero in uksouth-1/2), about 75% of all AzureUpfailures.3. Skip attach-flaky azuredisk storage tests. Azure serializes disk attach/detach per VM, so under high parallelism the attach-heavy
disk.csi.azure.comspecs (store-data, volume-expand, subPath, exec) time out. Anchored to the driver, so provisioning, topology, ephemeral, volumeMode and capacity specs keep running and non-azure drivers are unaffected./cc @rifelpet @ameukam
