Microsoft Azure Issue affecting NcasT4v3 Series Virtual Machines (West Europe)

Azure is currently experiencing Compute capacity constraints in the West Europe region. Starting as early as 05:30 UTC on 13 March 2026, users attempting to create, update, scale, start, and/or restart Virtual Machines in West-Europe region may experience allocation failures. 

Microsoft is experiencing regional deployment failures for AMD GPU SKUs. Constrained Virtual Machine series include: 

• NcasT4v3

At this time, you are not able to create or use VMs in myDRE with VM type: NcasT4v3. Please select another VM type.

This issue originates from Microsoft Azure. We are monitoring the situation and will provide updates as more information becomes available. You can also follow Microsoft’s official updates on their Azure status pages.

We apologize for the inconvenience. 

Current status: Due to an increase in demand for compute resources in the region, there are capacity constraints on available compute infrastructure. This in turn resulted in service management operation and allocation failures for VM resources. 

We are currently working on platform levers to restore healthy buffers in relation to capacity. We will continue to monitor the situation and supply updates accordingly.
