Consistent Network Connectivity
Multi-layer redundancy architecture ensures service continuity. Intelligent DNS selects optimal entry points, load balancers distribute traffic, and health checks run continuously. When a node fails, the system automatically switches to maintain uninterrupted connections.
Every Step of Connection is Protected
Intelligent DNS Resolution
When your device queries our domain, GeoDNS system:
- Identifies your geographic location and ISP network
- Calculates theoretical latency to each entry server
- Returns only healthy IPs with lowest latency
- Automatically switches on next query if preferred entry fails
Entry Load Balancing
After connecting to an entry server, load balancer activates:
- Multiple entry servers online simultaneously, sharing requests
- Each server handles traffic independently without interference
- Other servers continue service if any one fails
- Traffic dynamically allocated based on current server load
Backend Intelligent Routing
Entry server forwards your proxy request to backend:
- Backend maintains a pool of healthy proxy servers
- Selects optimal exit node based on destination
- Monitors latency and success rate of each node in real-time
- Abnormal nodes automatically isolated and recovery attempted
Comprehensive Real-time Monitoring
Latency Monitoring
Response time sampled every second for each node, immediate alert when threshold exceeded.
Packet Loss
Continuous network packet loss monitoring, abnormal nodes automatically degraded or removed.
Connection Success Rate
Tracks connection establishment success rate, automatic handling when below standard.
Resource Usage
Real-time CPU, memory, bandwidth monitoring, scaling triggered when approaching limits.
Health Checks
Active checks every 10 seconds on all nodes, removal from pool after 3 failures.
Traffic Analysis
Analyzes traffic patterns and user distribution, predicts and handles capacity needs proactively.
Automated Failure Handling
Issue Detection
Health check detects node timeout or error responses. Monitoring system immediately logs anomaly and begins impact assessment.
Automatic Decision
System determines if it's transient fluctuation or persistent failure. Failover triggered after 3 consecutive check failures.
Traffic Switching
Load balancer configuration updated, traffic shifted from failed to healthy nodes. DNS records updated accordingly.
Continuous Monitoring
Failed node enters isolation, system attempts automatic recovery. Rejoins pool after successful recovery, operations team notified if failed.
Technical Guarantee Details
Intelligent DNS System
- Multiple DNS servers deployed with GeoDNS and Anycast support
- DNS record TTL set to 60 seconds for rapid updates
- Failed health check IPs automatically removed from DNS responses
Load Balancing Strategy
- Multiple algorithms supported: round-robin, least connections, source hash

Health Check Mechanism
- TCP connection check: ensures port reachability
- HTTP probe: verifies service responds normally
- Failure retry strategy: 3 failures before marking unhealthy, avoids false positives
Monitoring Alert System
- Critical metric anomalies immediately notify operations team (email, SMS, enterprise messaging)
- All operations have audit logs for post-incident analysis and tracking
- Monitoring API provided for enterprise customers to integrate with their own systems
Frequently Asked Questions
Our entry servers are deployed across multiple data centers and different ISP networks. A single data center or network failure won't affect service. Even in extreme cases where all entries in a region are unavailable, DNS automatically redirects traffic to healthy entries in other regions.
For new connections, failover is completely transparent—users won't notice any change. For established long connections, reconnection may rarely be needed, but modern clients typically handle this automatically. The entire process usually completes within 30 seconds.
The monitoring system uses redundant design, deployed on infrastructure independent from business servers. We use multiple monitoring nodes checking service status from different locations, avoiding single points of failure and false positives from network partitions.
Backend server pool maintains sufficient redundant capacity—single or few node failures won't impact overall service. In case of large-scale failure, system automatically scales up backup resources. We also receive alerts and intervene manually.
