Hi @Sophia Leo ,
Thanks for reaching out to Microsoft QnA.
This issue is being reported by multiple customers and we are aware of this scenario and internally continuously working with the Product Team to drive these issues to a resolution. I understand you are seeing the VM sizes as unavailable in multiple regions, that is mostly because there is an extremely high demand for VMs in a lot of regions, which is creating capacity constraints.
Have you tried to check for availability of VM sizes in any of the below regions? Let me know if the VM sizes are showing unavailable in the below regions as well.
US East 2
US North Central
US West 3
We understand unavailability of VM sizes is creating inconvenience to our customers, but we are continuously providing feedbacks to the Product Team, in order to get this resolved as soon as we can.
Hope the provided information was useful.
