Understanding CDN

WHAT IS CDN?

A content delivery network speeds up your website by serving content closer to visitors

WHY DO YOU NEED IT?

1. A slow website frustrates your visitors
2. Site load times affect your search ranking
3. Spikes in traffic will crash your web server

WHAT ARE THE BENEFITS?

1. Pay as you go with low bandwidth costs
2. Make your own package and edit locations
3. Easy setup, reporting and 24/7 support

HOW DOES CDN WORK?

Your website’s content is securely cached on our servers. We detect the location of your visitors and then load the content such as videos, images, text and HTML from the closest server.

WHERE IS MY WEBSITE STORED?

When you have a website, it is hosted on a web server which you rent or buy from a hosting company. You pay for storage, bandwidth and CPU. You may have a dedicated server, a virtual private server, cloud server or a shared hosting plan. From your hosting provider’s control panel, you can manage your domain and hosting resources through a control panel. When you sign up for CDN.net, your website will be securely cached in locations around the world.

HOW DOES CDN CACHE MY CONTENT?

By simply entering your website URL or IP address, CDN.net ‘pulls’ all of the static content from your origin host and stores it on our edge servers located around the world. We are implementing support for ‘push’ which is appropriate for uploading large files to the edge servers and ‘stream’ for live video or sound broadcasts through HTTP or real time messaging protocols.

DO YOU HAVE TO MODIFY YOUR WEB SERVER?

By changing a CNAME record through your hosting provider’s control panel, known as a DNS editor or Zone File editor, you don’t need to change any part of your website. Your visitors will retrieve content cached from our network instead of your own web server.

HOW CAN YOU SECURELY DELIVER ANY CONTENT?

You can secure any content served through our network with an SSL certificate. We encrypt your images, video and other static content through HTTPS. Secure Sockets Layer (SSL) uses asymmetric cryptography for authenticating keys between a server and a user. You can use our shared SSL certificate for free or order a custom SSL domain through CDN.net.

HOW CAN YOU TEST YOUR WEBSITE LOAD TIMES?

We recommend Pingdom to monitor uptime and their free tools for testing page speed time. You simply enter your domain name and it will measure the size of each element on your page and their load times. This is independent testing that can show you how fast your site loads before and after implementing CDN. For a full list of monitoring tools for your site, see our blog post.

HOW MUCH DOES IT COST?

Our latest pricing packages are available on the PRICING page. We offer a range of packages from just $20 per month, but if you can’t find the right package for you just get in touch and we can create a bespoke package just for you.

WILL IT WORK WITH DIFFERENT SCREEN SIZES?

CDN.net will serve any static content regardless of the device or browser your visitors use. We recommend using JW Player and Wowza Media Server 3 for advanced video on demand functionality.

HOW DO I SET UP A CDN RESOURCE?

1. Select “Dashboard” – The dashboard displays your current balance and any other CDN resources you have created
2. Click “Create” – The create button is just under the balance and you can see it also under packages
3. Enter the “Origin Hostname” – The origin hostname is the URL where your content is stored e.e example.com
4. Enter the “CDN Hostname” – The CDN Hostname is the URL including a subdomain e.g. www.example.com
5. Update your CNAME records – We generate a CNAME record that you must add through your hosting provider’s DNS Editor in a control panel e.g. 12345678.r.worldcdn.net
