Content is not distributed in the Brazil South region.

**Describe the bug**

I am approving the implementation of Azure Static Web Apps, but most of my customers are in Brazil and it seems to me that the Global distribution is not serving Brazil.

**To Reproduce**

1. Deploy Azure Static Web App
2. Access through a region in Brazil.
3. Test CDN (https://www.cdnperf.com/tools/cdn-latency-benchmark/)
https://www.cdnperf.com/tools/cdn-latency-benchmark/?id=mt8el0m1go5hkg

5. See that in Brazil it is resolved with IP (20.75.112.13), hosted

**Expected behavior**
CDN must resolve to IP in a datacenter in the Brazil region.

**Additional context**
I would like to understand why the Global Azure Static Web Apps resource does not resolve the CDN with an IP from a region in Brazil.

Reproduce the deployment and access steps in the issue from Brazil, then review the linked CDN latency benchmark and the observed IP address 20.75.112.13. Determine whether Azure Static Web Apps Global distribution supports a Brazil datacenter endpoint or whether this indicates a service issue; done means documenting the cause and the expected regional behavior.
