Overall experience improves efficiency and lowers operational challenges
* Add native management routing (geo‑routing, failover, weighted records) directly within Azure DNS zones to reduce dependency on extra services. * Cost Efficiency: Offer bundle pricing tiers or discounts for high‑volume enterprise customers, or an option for cost‑optimized internal DNS zones. * Improved Error Diagnostics: Provide more descriptive error codes and guided troubleshooting steps in the portal or CLI.

Intelligent traffic steering has improved uptime and now needs simpler policies and support
The best features IBM NS1 Connect offers include the authoritative DNS filter chain, traffic steering policies, and endpoint health monitoring, along with its API-first automation and DNS reporting, which are all some of the most valuable features. Out of those features, I find myself relying on the traffic steering policies the most because we detect the endpoints and steer new DNS responses towards healthy alternatives. This is very helpful because whenever there is a massive amount of requests coming into the region or to the server, and for a better user interface and customer experience, we should not show the user that the server is down. We can reroute the request to the server nearest to that region, making it an important capability. The authoritative DNS ensures DNS queries for domains and reliable DNS resolution are essential for users, particularly to discover application endpoints, but it alone does not guarantee this. The API-first automation automates DNS configurations and changes through APIs and infrastructure as code workflows, reducing repetitive manual work and the risk of human error. The DNS reporting and analytics help teams understand query volume, traffic distribution, and unusual behavior under the support of troubleshooting and capacity planning.
