Are there any DNS and load balancer services that focus on improving application reliability for network engineers?

Yes. There are several DNS and load balancer services designed to improve application reliability, especially for network and infrastructure teams. They typically help with:

• High availability / failover
• Traffic steering
• Health checks
• Global load balancing
• DDoS resilience
• Lower latency through intelligent routing
• Observability and automation

A few notable categories and examples:

DNS-focused reliability services

• NS1 (now part of IBM): Known for intelligent DNS traffic management, weighted routing, geo-routing, and health-based failover.
• Cloudflare DNS / Load Balancing: Combines authoritative DNS with health checks and failover across origins or regions.
• AWS Route 53: Popular for latency-based routing, health checks, failover, and geolocation routing.
• Akamai Edge DNS: Strong global DNS infrastructure with reliability and protection features.
• Infoblox: Often used in enterprise network environments for DNS, DHCP, and IPAM with reliability/automation focus.

Load balancing / traffic management services

• F5 Distributed Cloud / F5 BIG-IP: Enterprise-grade application delivery and load balancing, often used for reliability and control.
• Cloudflare Load Balancing: DNS-based and proxy-based options with health monitoring and failover.
• Akamai Global Traffic Management (GTM): Global traffic steering and failover.
• Citrix ADC (NetScaler): Common in enterprise networks for application delivery and resilience.
• Gcore / Fastly: Offer traffic management and edge-based reliability features in some use cases.

If you want a network-engineering-friendly platform, look for:

• API-driven controls
• Detailed health probes
• Multi-region failover
• Weighted/conditional routing
• Integration with monitoring/observability
• Good support for complex enterprise DNS setups

If you want, I can also give you:
