Powering multi-edge resilience with DNS

IO River uses IBM NS1 Connect to enable granular, resilient traffic steering.

Turning complex edge policies into DNS logic

IO River enables organizations to unlock the full potential of multi-edge architectures by intelligently routing traffic and deploying compute across multiple edge providers. As multi-edge strategies grow more complex, traffic steering policies must optimize for performance, cost and availability—at scale.

These highly granular policies must ultimately be executed at the DNS layer, where even small limitations can affect uptime and user experience. Previously reliant on a single DNS provider, IO River faced constraints around redundancy and flexibility. Because DNS is a critical dependency, any weakness could directly impact traffic routing, platform reliability and customer confidence.

Integrating API-driven DNS for multi-edge

IO River selected IBM® NS1 Connect® for its flexibility, configurability and clean API integration. Other providers required more complicated implementations and lacked the functionality to support high-granularity routing logic.

IO River integrated IBM NS1 Connect Traffic Steering directly into its platform, transforming DNS from a static configuration layer into a dynamic decision engine. Using NS1 Filter Chains, IO River translates complex, customer-defined policies into precise DNS logic, including ASN-based routing. The integration improved redundancy, reduced reliance on a single DNS provider and enables the platform to scale as new edge providers and routing strategies are introduced.

Stronger resilience and scalable growth

Since implementing IBM NS1 Connect, IO River has experienced 100% uptime. The architectural impact was immediate, strengthening availability across its edge layer and improving overall platform resilience.

With multi-provider DNS support, IO River reduced dependency risk and increased confidence in reliability for both internal teams and customers. DNS is no longer a limiting factor but an enabler of advanced traffic routing capabilities, including ASN-based steering. The platform now has a scalable foundation to support future performance optimization and the growing demands of multi-edge architectures.
