Hi @Malvaro ,
It looks like Sam already answered your question in this post: https://learn.microsoft.com/en-us/answers/questions/1190734/static-web-app-global-resource
"Resource groups always exist in a specific region, however if you deploy global resources to that resource group they are not tied to that region and would not be affected by an outage in that region. You do not need to deploy multiple static web apps."
please let us know if you have further questions.
Thanks,
Grace
