Advantages of a global CDN

What is a CDN and why is it used?

A content delivery network (CDN) is a network of servers located in various data centres around the world. This makes your website load faster, especially if the website visitor is not located close to your web server. Your customers benefit predominantly from quick loading times and a smooth-running website. This gives you a decisive competitive advantage.

In addition, the network offers a higher level of security for your web server and therefore for your website. The CDN can detect attacks on your site early on and fend them off. In addition, the distribution of data traffic over a wide network means that your own web server is better protected.

How does a CDN work?

As soon as a visitor accesses your website for the first time, the CDN transfers the static content of your page from your web server to its cache memory. Numerous data centres in the CDN worldwide can access these caches. For example, if a potential customer in South Africa visits your online shop to send a birthday gift to the UK, your page will be loaded from a data centre in South Africa. This ensures that your website always has short loading times, no matter where it is accessed.

The CDN not only ensures a geographical proximity between visitor and server, it also enables requests to your website to be better distributed on the worldwide data highway. The network can handle periods of heavy traffic without difficulty since it is able to distribute the access attempts to servers with free capacities. The system always searches for client-server connections that are less busy than others. Requests are therefore always answered as quickly as possible.

Fast loading times, every time

The content delivery network checks the CPU utilisation of the CDN servers and the number of active visits to your website. Servers with free capacity are identified and the routes with the fastest and geographically closest connections between users and servers are found. All this happens in a fraction of a second – and means quick loading times for your visitors.

Static elements such as images and Flash animations, which normally load more slowly than text content, are cached in the content delivery network and can therefore be retrieved from any CDN server. Even websites with a lot of dynamic content load faster in a CDN, regardless of their location.

This network provides content in closer proximity to the visitor, reducing latency and shortening the time it takes for the first byte to be received. Cloudflare’s size and the way its internet connections are distributed provide customers around the world with fast, reliable delivery.

Content delivery network - FAQ

If, for example, you operate an online shop that regularly generates visits from customers all over the world, then using a content delivery network could be very helpful for you.

Since the loading speed of a website is critical for a business, your online shop should load just as quickly for users in Australia as for users in the United Kingdom. If it doesn't, you could lose this customer to another online shop that has faster-loading content. In other words, the more your clientele is spread around the world, the more you should rely on a CDN.

The content delivery network also provides quicker loading times for websites that have a lot of dynamic content. But websites with static content such as images and Flash animations or JavaScript elements also load faster thanks to the CDN. The same applies if the number of website visitors is extremely high at peak times. By distributing the different access attempts over the network, the loading speed always remains constant.

You can easily activate CDN hosting via the IONOS Help Centre. In your package details, you will find information on whether you already have CDN hosting included. If you are unsure which packages allow you to use a content delivery network, our support team will be happy to assist you at any time.

Yes, although there is one exception: the free basic version CDN powered by Cloudflare does not support SSL encryption. The CDN Plus package, on the other hand, includes SSL encryption, which helps you protect the data traffic between your website and its visitors. This means that sensitive information can be securely transmitted, authenticated and managed.

  • First, book the appropriate hosting plan for your needs and make sure that it includes the use of a content delivery network.
  • If you already have a package that allows CDN use, you can book CDN Plus at any time in the IONOS customer shop.
  • Activate your CDN Plus package with just a few clicks via your control panel.

Then select the SSL encryption you want from the two options. Depending on the option, you may also need your own IONOS SSL certificate for your CDN. This can also be booked at a low price or you can activate it immediately if the certificate is already included in your package.

We have compiled more information on CDN and SSL encryption, as well as additional links, in the IONOS Help Centre.

Yes, of course you can. However, depending on the size of and amount of traffic to your website, you do risk a noticeable deterioration in loading time. If your competitors use a CDN and therefore provide their users and customers with faster access times to their content, offers, and services from any location, you will suffer a competitive disadvantage.

Long loading times can cause users and potential customers to jump ship. If, for example, you're hosting a US website without using a CDN, visitors from abroad – especially from far-away countries – may notice significantly longer loading times. This usually leads to an increased bounce rate. With a content delivery network, a network of servers in different data centres all over the world, and correspondingly fast loading times, risks like these can be minimised.

Yes, millions of websites worldwide are based on WordPress – so it's not surprising that super-fast CDN hosting with WordPress is possible without much effort. After all, these websites need to be competitive – and quick access times, high security and maximum availability are among the critical success factors. Numerous providers therefore offer corresponding CDN solutions for WordPress and almost every CDN WordPress plug-in has its own integration method.
