RockCloud · Global acceleration network

“RockCloud is engineered for workloads that live and die by speed. Our global CDN runs on Anycast routing and a private backbone that keeps latency to a minimum for every visitor.

Intelligent route selection across thousands of directly connected ISP nodes puts your content on the fastest available path, whether the request crosses continents or stays local.”

Routing and connectivity

Tier-1 transit providers and private network interconnects blend into the local network at every location. Combined with latency-based routing, every packet travels the shortest path available.

Latency-based routing

Real-time monitoring of 150,000+ source/destination IP pairs lets us collect latency and connection-quality data from every location.

Analysing more than 600,000+ netflows every second, we steer each visitor to the lowest-latency endpoint automatically.

Direct interconnection with Tier-1 carriers

Our upstream includes 14 Tier-1 transit providers plus private network interconnects with more than 300 global ISPs.

Global private
acceleration backbone

RockCloud operates a dedicated backbone built on n × 100GE infrastructure worldwide. It links every core PoP and underpins the 15 Tbps of CDN delivery capacity.

Our tightest global backbone circuits are only a few hops apart, and CN2 private lines connect them straight into mainland China.

Cache servers inside ISP networks

Beyond the PoPs marked on the map, more than 60 cache clusters sit directly inside ISP data centers. Keeping content as physically close to the visitor as possible delivers the best performance, even in hard-to-reach destinations.
