Ever wondered how we route billions of requests per day across 285+ edge locations? This deep dive explains our network architecture.
Anycast Routing
We use BGP anycast to announce our IP addresses from all edge locations. When a user makes a request, they are automatically routed to the nearest healthy edge node.
Intelligent Load Balancing
Beyond simple geographic routing, we consider server load, network conditions, and origin health when making routing decisions.
Edge Node Architecture
- Multi-tier caching (memory, SSD, HDD)
- Custom HTTP stack optimized for CDN workloads
- Hardware-accelerated TLS termination
- Real-time metrics collection
Reliability
Each edge location runs in active-active configuration with automatic failover. We maintain N+2 redundancy for critical components.
