About

Azure CDN

Azure CDN is an independent content delivery network. The name refers to the color azure (sky blue), not to any other company or cloud platform.

We operate 20 edge nodes across 14 cities in North America, Europe, Asia Pacific, and South America. Traffic routes via BGP anycast to the nearest healthy PoP. Origin shield reduces load on your servers by consolidating cache misses through a single intermediate node.

The service handles static asset delivery, dynamic content acceleration, and DDoS mitigation at the edge. Automatic TLS provisioning is included for all zones.

SLA

Azure CDN commits to the following service level targets:

• 99.99% monthly uptime for the edge network
• 99.95% monthly uptime for the API and dashboard
• Cache purge propagation within 10 seconds to all PoPs
• TLS certificate issuance within 15 minutes of CNAME verification

If monthly uptime falls below the committed threshold, affected accounts receive service credits proportional to the downtime duration. Credits are applied automatically.

Infrastructure

Edge nodes run on bare-metal servers in carrier-neutral data centers. Each PoP has N+1 redundancy with dedicated transit links to at least two Tier 1 providers. Storage is NVMe-backed for cache, with in-memory caching for frequently accessed objects.

Total network capacity: 4 Tbps. Current peak utilization: approximately 18%.
