Use cases

Improve reliability and resilience

Keep users connected and revenue flowing with a global anycast network featuring a 100% DNS uptime service level agreement (SLA). DNS servers can be subject to attacks that deny access to domains, overwhelm servers with traffic or take over DNS infrastructure. NS1 provides built-in resilience against distributed denial of service or DDoS attacks, including volumetric DDoS surges for improved DNS security. For added resilience, an optional single-tenant redundant domain name system (DNS) layer is also available.

Optimize DNS infrastructure

Your anycast DNS solution needs to have advanced, customisable traffic steering, Real User Monitoring (RUM), global server load balancing (GSLB DNS) and multi CDN capabilities to help ensure that you can deliver applications, services and content with the performance your users expect.

Enhance DNS with network observability

Automate DNS management and gain real-time visibility with the IBM® NS1 Connect® API. Streamline primary and secondary DNS tasks while integrating observability tools to detect, diagnose, and resolve issues faster—reducing manual effort and improving operational resilience. 

Optimize CDN performance and delivery

Maximize performance and reliability with IBM NS1 Connect's multi-CDN steering. Intelligently route traffic across multiple CDN providers using real-time performance and availability data. Leverage Real User Monitoring to automatically direct users to the fastest, most reliable CDN available. Reduce latency, prevent outages, lower costs, meet usage commitments and optimize global delivery.
