Content Delivery Networks: Speeding Up the Web Content Delivery Networks (CDNs) place copies of your content in many locations around the world. This makes pages load faster for visitors who are far from your main server. CDNs handle many requests at once and serve content from a nearby edge location. They also help your site scale during sudden traffic surges. How they work: When a user requests a file, the CDN routes the request to the closest edge server. If the edge has a fresh copy, it serves immediately. If not, it fetches from the origin, stores a copy, and serves it. Popular files stay near users, while less-used content stays on the origin until needed. ...

The goal is to minimize latency, while keeping assets fresh and secure, even during traffic spikes. Choose a base CDN with broad coverage and reliable edge capacity. In regions with high demand, add a second CDN or use a multi-CDN approach. DNS-based steering or latency-aware routing helps direct users to the nearest edge, reducing round trips and improving first-byte times. ...
