Instance Size Flexibility update

[eltanko]

We have received a Service Health alert in our Azure portal detailing the ISF file will no longer be available and to use the Catalog API.

Does this affect the open data file that FinOps Hubs (we're on v13 with Data Explorer) connects to that's in the ccmstorageprod blob storage account?

_You're receiving this notification because you’re associated with one or more Azure subscriptions using Azure Virtual Machine Reserved Instances.

After 9 May 2026, the instance size flexibility ratio file will no longer be updated in our documentation. To access the latest instance size flexibility ratios, you’ll have to use the Azure Catalogs API. Read this documentation page for details on using the API.

You may continue using the current instance size flexibility file until 30 August 2026. However, if your organization relies on this file for internal billing processes or cost management tools, we recommend transitioning to the new API as soon as possible._
