What is a CDN?
A Content Delivery Network (CDN) is a global network of servers that stores cached copies of your website's static files — images, CSS, JavaScript, and fonts. When a visitor loads your website, the CDN serves those files from the server geographically closest to them rather than from your origin server.
Why Does Location Matter?
Every millisecond of network latency adds up. A visitor in Chennai loading files from a server in the US experiences 200–300ms of additional delay per request. With a CDN, that same visitor loads files from a CDN node in India in under 20ms.
What a CDN Does Not Do
A CDN caches static assets — it does not replace your web hosting. Your actual server still handles dynamic requests (like WordPress PHP pages or API calls). The CDN sits in front of your server and offloads the heavy, repetitive work.
Key Benefits of Using a CDN
- **Faster page loads** — Static files load from the nearest edge node
- **Reduced server load** — Up to 80% of bandwidth handled by CDN
- **Better Core Web Vitals** — LCP and FCP scores improve measurably
- **DDoS protection** — CDNs absorb traffic spikes and filter malicious requests
- **Global reach** — Your site is fast everywhere, not just near your server
