CDN Edge Locations & Points of Presence
Understand how a CDN distributes servers geographically through Points of Presence (PoPs) and edge locations to bring content physically closer to users.
What Is a Point of Presence?
A Point of Presence (PoP) is a physical data center location where a CDN places its edge servers. Each PoP caches copies of your content so requests can be served from a nearby location instead of your distant origin server.
- PoPs are spread across cities and regions worldwide
- Each PoP contains one or more
edge servers - The goal is to shorten the network path between user and content
Edge Locations Explained
An edge location is the specific server within a PoP that actually stores and serves cached content. When a user requests an asset, the CDN routes them to the closest healthy edge location.
This reduces round-trip time (RTT) and lowers latency dramatically compared to fetching from a single origin.
