What is a CDN?

A CDN stands for content delivery network. Instead of your website living on a single server in one place, a CDN keeps copies of it on many servers in different cities and countries. When someone visits, they're served from the nearest one. This shortens the distance your data has to travel, so images, text, and pages appear more quickly no matter where the visitor is. A shopper in Milan and a shopper in New York both get a fast experience, even if your original server sits far from either of them.

Speed isn't a nice-to-have. Slow pages frustrate visitors and can quietly cost you sales, and search engines factor loading speed into rankings through measures like Core Web Vitals. A CDN also helps your site stay online during traffic spikes, because the load is shared across many machines rather than one. For a small business, all this happens invisibly. You don't manage the servers or the copies. It's simply part of good web hosting, quietly making your site quicker and steadier for real people.

With Promino, a global CDN is built in. Every published site is automatically served from servers close to your visitors, so your pages load fast worldwide without any setup on your part. There's nothing to configure and no extra cost to weigh up.

Fast delivery, caching, and reliable uptime all come as standard, letting you focus on your content rather than infrastructure. Learn more about web hosting in Promino.
