automatic provider fallback

Automatic provider fallback ensures 100% uptime by instantly rerouting traffic to a secondary carrier if your primary link drops.

Network reliability depends on redundancy. Automatic provider fallback uses real-time health checks (ICMP or TCP probes) to monitor connection stability. If latency spikes above 150ms or packet loss exceeds 2%, the system triggers a sub-second failover to a secondary ISP like Lumen or Zayo. This logic prevents session timeouts for critical applications (SaaS tools or VoIP calls) by maintaining the IP session state across diverse backbones. It is the standard for high-availability environments where a single fiber cut cannot be allowed to halt operations.
