Region-access support requests for PostgreSQL Flexible Server are stuck in an AI triage loop

You have already followed the documented region-access route, but the request is cycling through automated replies without an assigned engineer. The CLI message means provisioning is restricted for that subscription and region; it is not something an ARM template, role change, or CLI setting can bypass. First confirm Microsoft.DBforPostgreSQL is registered and that the request was opened under Azure Database for PostgreSQL Flexible Server, naming East US, the required vCore count, SKU, availability-zone needs, subscription ID, and CLI error. Add those facts and the nine-day timeline to the case, then explicitly request manual review and protection from automatic closure. Avoid opening duplicate requests, because that can split the history. There is no documented customer-side command that grants regional access. If deployment cannot wait, test an approved region and update the architecture for latency and residency. Only Microsoft support can approve capacity access or explain why the request is stalled.
