-Resizing alerts are triggered for the control plane nodes in a cluster when either of the following scenarios are true: 
+The resizing alert is triggered for the control plane nodes in a cluster when the following occurs:
 
-* Each control plane node has less than 16GiB RAM, and there are more than 25 and less than 101 compute nodes.
-* Each control plane node has less than 32GiB RAM, and there are more than 100 compute nodes.
+* Control plane nodes sustain over 66% utilization on average in a classic ROSA cluster.
