KeyCDN Review: The Perfect CDN For WordPress

KeyCDN is a service of Proinity Ltd, Swiss company, with its headquarters located in Winterthur. KeyCDN offers high performance Content Delivery Network packages at a very competitive price. In this KeyCDN review, we will scrutinize every aspect of KeyCDN’s offering in order to validate the claims of the company and examine the performance of the content delivery network.

In order to understand the importance and excellence of this network, certain questions need to be answered first.

What is a Content Delivery Network or CDN?

CDN is a system of servers spread over the world in multiple data centers across the internet. These servers connect you to the nearest point of presence or POP and helps improve the speed of your connection. It serves almost all sections of the internet. It includes all web objects, downloadable objects, applications, live streaming media, social networks and so on.

Why do you need CDN?

CDN is beneficial to you in a number of ways

  • It accelerates your content.
  • It will allow you to scale seamlessly as it reduces operational costs.
  • If you have a close POP, it reduces loading time, lower latency and minimized package loss.
  • It will reduce the load on your server, thereby giving your site visitors a seamless browsing experience.

What You Get With KeyCDN

KeyCDN are not claiming they are the best Content delivery network in the market, their unique value proposition is competitive pricing. KeyCDN offers the lowest price you can find on the market, I would avoid tagging it a cheap CDN as that could be mistaken for poor performance but it certainly wins in the competitive pricing category.

Shared SSL

KeyCDN offers every customer shared SSL for free.

Custom SSL Certificate

If you already have your own SSL certificate, it is integrated for free.

Let’s Encrypt

As of December 14th, 2015 KeyCDN now has Let’s Encrypt integration. Basically, this means you can now have a custom SSL certificate for free! I have a Let’s Encrypt certificate running on this blog.

Block Bad Bots

As of February 9th, 2016, they also now have a feature to block bad bots. This allows you to save money on your CDN bandwidth.

KeyCDN Review

keycdn review
Tests carried out using
  • Large file download tests the best services for larger file downloads (e.g. video streaming)
  • Small file download tests the fastest services for a web app or website (web pages typically consist of many small files)
  • Network latency tests the overall responsiveness of a service and is generally most affected by geographical proximity

Apart from the performance test carried out through Cloudharmony we also deployed KeyCDN on this website for the purpose of this KeyCDN review and the results were pretty impressive. Compared to the Jetpack free photon CDN, we experienced faster page load and a significant reduction on server load when using KeyCDN.

  1. What happens when a user uploads a big file, and it takes a couple of minutes for KeyCDN to catch up, right? And until then everyone visiting the site will get an “image not found error”..??

      • Why would you want to use two? Your post says KeyCDN has free SSL too…

        Has anyone done any decent speed testing between the two?

        • Some people prefer Cloudflare for DNS side of things. For CDN portion, it would be better just to use one or the other. In my personal experience, I have seen horrible TTFB with Cloudflare. I actually have a draft post of Cloudflare vs KeyCDN. Need to finish it writing it :) I actually haven’t seen any good blog posts comparing the two yet. And yes, KeyCDN has free shared SSL. And then custom SSL integration is free.

          • Yeah, a data-driven comparison between them would be great. I did some similar testing between WP hosts a few weeks back, and was surprised that cheaper hosts did better than more expensive, bigger name managed WP hosts (Lightning Base [$10/mo] did better nationally, while Flywheel [$15/mo] did better in the NY, NJ, VA area), or at least the ones under a hundred plug bucks a month.

            Finish it and share :)

            BTW, I just tried to subscribe to your blog by email and the email subscribe widget wasn’t working. I followed you on Twitter though ( @ Ndvrer ), and added you to one of my WordPress lists.

          • Ya, I have been moving some smaller clients to InMotion Hosting and was blown away by the speed. And they are one of the only independent ones left not owned by EIG. I have yet to try Flywheel, as I am pretty with Kinsta. But ya there are some cheaper hosts out there that are really doing good.

            I will finish the post up :)

            Sorry about that, I got a little over excited with caching and concatenation lol… should be working now, had to rearrange some of the files in the footer. Console was spitting up errors. Thanks for the follow!

          • Brian, I’m very interested in using KeyCDN and CloudFlare together but can’t find any clear instruction on how to implement the 2. Please, please point me to some clear instruction on how to set them up the way you were hinting at above. I would greatly appreciate it.
            I’m trying to integrate my WP sites with S3, KeyCDN and CloudFlare and don’t know how to do it. I’m totally new to CDN. Right now I’m just using my dedicated hosting and S3 for some files. Thanks for your help.

          • Thanks so much for your quick reply Brian. So, with the info from above and the link that you provided, I should be good to go?

            Also, which of these should I use (WP Super cache or W3 Total Cache)?

            And how should I go about using my S3 audio, image and video files? I’m I linking them to KeyCDN or CF?
