Point of Presence (PoP)

A Point of Presence (PoP) is a physical location — typically a rack or suite inside a carrier-neutral or colocation data center — where a network operator, cloud provider or CDN terminates its own infrastructure to connect with other networks and customers in that market. A PoP lets a provider claim local presence (lower latency, in-region compliance) without building a full data center: it usually holds routers, switches and a handful of racks rather than a full data hall. Cloud providers publish PoP counts as a proxy for edge reach — hyperscalers and major CDNs each operate hundreds of PoPs across metro markets worldwide — and enterprises choosing a colocation facility often check which PoPs are already on-site, since reaching a carrier or cloud on-ramp inside the same building avoids a cross-connect fee and metro-fiber latency. PoPs cluster inside carrier hotels and meet-me rooms precisely because proximity to many other networks' PoPs is what makes an exchange point valuable.
