+### Right-size underutilized App Service plans
+
+We've analyzed the usage patterns of your app service plan over the past 7 days and identified low CPU usage. While certain scenarios can result in low utilization by design, you can often save money by choosing a less expensive SKU while retaining the same features.
+
+> [!NOTE]
+> - Currently, this recommendation only works for App Service plans running on Windows on a SKU that allows you to downscale to less expensive tiers without losing any features, like from P3v2 to P2v2 or from P2v2 to P1v2. 
+> - CPU bursts that last only a few minutes might not be correctly detected. Please perform a careful analysis in your App Service plan metrics blade before downscaling your SKU.
