This post is part of my Website Foundations series — a practical guide for business owners and website owners who want to better understand the tools and systems behind a successful website. Today, we’re breaking down something that is a bit technical, but it can help with the performance of your website, especially if you have visitors from different countries or territories.
What Is a CDN?
CDN stands for Content Delivery Network. It’s a network of servers located around the world that work together to deliver your website content to visitors faster.
Instead of every visitor accessing your website directly from your main hosting server (which might be in New Zealand or overseas), a CDN stores cached versions of your content in multiple locations worldwide — and serves it from the closest one.
Think of it like this:
Without a CDN = one slow road to your website
With a CDN = multiple express lanes to your content
What Does a CDN Actually Do?
A CDN helps with:
Speed: Visitors load your website faster, especially if they’re far from your hosting server
Performance: Reduces the load on your main server, so your site runs more smoothly
Reliability: Can help your site stay online during traffic spikes or unexpected surges
Security: Many CDNs offer built-in protection against DDoS attacks and malicious traffic
Who Benefits Most from a CDN?
If your website:
- Attracts visitors from multiple regions or countries
- Uses lots of images or media
- Has a global audience
- Experiences spikes in traffic
- Needs to load quickly for SEO or user experience
…then a CDN can be a valuable addition.
Even smaller, local businesses can benefit from a CDN especially if their hosting provider is located overseas or if their website is image heavy.
Do You *Need* a CDN?
Not every website *needs* a CDN, but many benefit from one.
If your site is hosted on a fast, local server and serves a small audience in one region, you might not see a big difference. But if speed, performance, or security are important to your business, a CDN can help take your website to the next level.
Many modern hosting providers now include CDN functionality as standard or make it easy to integrate with popular providers.
What I Recommend
When I host or manage websites for clients, a CDN is typically included as part of the service. It’s one of those invisible tools that helps keep your site fast, secure, and resilient — without you needing to worry about it.
If you’re unsure whether your site is using a CDN, or if it could benefit from one, I’m happy to take a look and advise you.
