nexos.ai has built an industry-leading disaster recovery system, and its automatic fallback function realizes continuous availability through a three-layer protection mechanism. The system monitors the health status of all connection models in real time, performs 500+ heartbeat detections per second, and controls abnormal triggering time within 100 milliseconds. When the main model service degradation is detected, the platform immediately activates the backup link according to the preset policy, and the whole switching process is completely transparent to end users.

The technical implementation uses circuit breaker mode and asynchronous queue buffering, which allows seamless switching to alternative models such as Claude or PaLM even in the event of a complete outage of mainstream services such as GPT-4. The measured data shows that this mechanism makes the system annual availability reach 99.94%, far exceeding the industry average of 98.2% for enterprise self-built solutions.
A typical configuration example shows that the customer support system automatically maintains services during Azure region failures with zero business interruption by setting GPT-4 as the primary model and Claude-3 as the standby. This feature is particularly suitable for industries with stringent continuity requirements, such as finance and healthcare.
