Hi Cody,
In my experience East US has been blocked for MySQL Flexible for many months now.
Please carefully follow my instructions below to create a new Service and subscription limits (quotas) request to allow access to deploy Azure Database for MySQL Flexible Server in East US.
1. Navigate to this link to start the process:
https://portal.azure.com/#view/Microsoft_Azure_Support/HelpAndSupportBlade/~/overview
2. Click Create a support request button at top
3. If you see Support AI Assistant as shown below, click Switch to old experience button on right. If not, proceed to step #4
4. Enter subscription limit in the box and click Go
5. Click Create a support request button, as shown
6. Select Issue type: Service and subscription limits (quotas), Subscription, Quota type: Azure Database for MySQL Flexible Server, click Next
7. Now you should be on Additional details tab. Click Enter details
8. Select Region access or Region access with zonal dependency, select Location you need (East US), enter number of cores, click Save and continue
9. Finish filling out Additional details tab, click Next, review and click Create. You should receive an automated email within a few minutes.
