CDN stands for Content Delivery Network. It sounds technical, but the concept is straightforward — and understanding it helps explain why some websites load almost instantly while others feel sluggish.
The problem a CDN solves
When someone visits your website, their browser requests files from a server. If that server is in one location — say, a data centre in London — visitors close to London get a fast response. Visitors further away (or on slower connections) wait longer.
A CDN solves this by copying your website's files to a network of servers distributed around the world. When someone visits your site, the CDN serves the files from whichever server is geographically closest to them, reducing the distance data has to travel and making pages load faster.
Why it matters for your business
Faster loading means:
- More visitors stay — people don't abandon your site before it loads
- Better Google rankings — page speed is a direct ranking factor, and CDN-backed sites score better on Core Web Vitals
- Better mobile experience — mobile connections are often slower; a CDN helps compensate

CDNs and security
CDNs also provide a layer of security. Cloudflare — the most widely used CDN — includes DDoS protection, which shields your site from malicious traffic attacks that can slow it down or take it offline.
What NC Digital uses
Our website hosting includes Cloudflare's CDN as standard — there's nothing extra to set up or pay for. It's part of what makes our hosting genuinely fast rather than just claiming to be.
Hosting is £20/month or £220/year for custom and WordPress sites, and is built into our managed starter websites package.
