Edge Servers Around the World

CDNs run thousands of edge servers in data centers across continents so content can be delivered from a location close to each visitor. The closer the edge is to the user, the fewer network hops and the lower the round‑trip time.

When a request arrives, the CDN routes it to an optimal edge based on latency, capacity, and network conditions. This routing can change dynamically as traffic shifts or outages occur.

Because edges are distributed, they also add resilience: if one region has trouble, traffic can be steered to healthy points of presence while still keeping performance acceptable.
