      The cluster-dns-operator was previously setting the service.kubernetes.io/topology-aware-hints annotation on DNS service without considering the number of availability zones. This caused clusters in which all nodes had the same topology.kubernetes.io/zone label value to emit "TopologyAwareHintsDisabled" events repeatedly. The cluster-dns-operator now ensures the nodes belong to different zones when setting the service.kubernetes.io/topology-aware-hints annotation.

          Bug - A problem that impairs or prevents the functions of the product. OCPBUGS-20024 Excessive TopologyAwareHintsDisabled events due to service/dns-default with topology aware hints activated.

          • Normal - To be worked after urgent and high priorities are resolved. This term is chosen when the severity of an issue is relatively close to the level of effort to fix it. The existence of an easily implemented workaround can also lead to this priority level instead of a higher priority.

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
