TL;DR: if you need the quick unblock for Azure-hosted CI, run: az sql server firewall-rule create --resource-group YOUR_RG --server YOUR_SERVER --name AllowAzureServices --start-ip-address the all-interfaces address --end-ip-address the all-interfaces address. The the all-interfaces address to the all-interfaces address range is special in Azure SQL, its the switch for Allow Azure Services, not a real IP range.

## Fix
1. if you need the quick unblock for Azure-hosted CI, run: az sql server firewall-rule create --resource-group YOUR_RG --server YOUR_SERVER --name AllowAzureServices --start-ip-address the all-interfaces address --end-ip-address the all-interfaces address.
   Expected: this specific failure stops.
2. The the all-interfaces address to the all-interfaces address range is special in Azure SQL, its the switch for Allow Azure Services, not a real IP range.
   Expected: the request routes instead of erroring.
3. Know the tradeoff before you use it: it lets every Azure service and resource reach your server, not just your runners.
   Expected: this specific failure stops.

## When to use
You hit exactly this: Azure SQL the all-interfaces address firewall rule: what the Allow Azure Services trick actually does in Azure SQL.

## When not to use
A different error, or the same symptom in a different tool. This page only covers the failure above.

## Compatibility
Azure SQL.

## Edge cases
- For production databases prefer the scoped approach, a rule for the specific runner IP that gets created and deleted by the deployment job, and keep the the all-interfaces address trick for dev and staging where the convenience is worth it.
