Hi @QuangThanh,

Before resizing the capacity, i would recommend you must double verify this upgrade by Microsoft.  
If you have fabric capacity metric app installed, please check the consumption of CU before 11 Aug 2026 and after that date and filter to warehouse level consumption which gives the accurate results.

I would suggest to open a Microsoft support case if this is causing your F64 to throttle.

The timing and cross-warehouse impact are strong enough to open a Microsoft support ticket that I would ask Microsoft to confirm whether a backend Warehouse change or consumption-rate/attribution change was deployed around August 11, 2026 or not and Fabric throttling occurs when consumption exceeds the capacity's available CU resources.  So this help to solve the concern of fabric capacity stability is legitimate.
