What is a CDN, and why it speeds up your website

A CDN (content delivery network) is a network of servers around the world that store copies of your website. When someone visits, they're served from a location near them — so your site loads fast wherever your customers are.

Why it matters

• •Faster load times for visitors far from your main server.
• •Better reliability — traffic spikes are handled across many servers.
• •Improved Core Web Vitals, which helps SEO.

Do you need one?

For most business sites, yes — and good modern hosting includes a CDN by default, so you get the speed benefit without configuring anything. It's one of the quiet reasons a well-built site feels instant.
