Slow CDN Servers of WordPress can bog down your website.

Recently, I published a list of few good and free blogging platforms. In that list, I rated very high. WordPress is indeed a great, stable, extendable and scalable platform for creating blogs and websites. Moreover, Automattic, the company behind WordPress, allows anyone to download WP and create self-hosted websites.

Self-hosted WordPress works excellently but sometimes user face a problem with domains and not working. These domains are sometimes found to be (very) slow. If you are doing a speed analysis of your website, you may find that is taking forever to respond. Let’s see the cause behind this sluggish problem!

Well, Automattic has setup several servers around the world. is a domain owned by Automattic. From these servers the company operates a Content Delivery Network (CDN) to swiftly deliver resources required by its software. So, first of all, you should know that and are indeed CDN servers of Automattic.

Slow CDN Servers of WordPress can bog down your website.

Slow CDN Servers of WordPress can bog down your website.

A couple of years ago, Automattic released an army of plug-ins modules to further extend the functionality of WordPress. These plug-ins are bundled and named as JetPack. No doubt, JetPack is very useful. Once installed, this plug-in allows you to activate and deactivate a large number of plug-ins developed by Automattic. However, in my experience, these plug-ins are slow.

The question is WHY?

The reason is that the JetPack modules get their supporting filed from Automattic CDN hosted on servers. More often than not, servers are found to be extremely slow. As a result, the websites using JetPack plug-ins will also get slow.

So, if you’re using a JetPack module and if this module requires a resources (like an image or CSS) from CDN… and if the CDN is responding slow… your website’s pages too will load very slow.

What’s the solution?

Because and servers are beyond your control, you can not do much.

The only thing you can do is that you can deactivate useless and not-so-important JetPack modules. To get rid of slowness due to the mentioned servers, you will have to deactivate all the JetPack modules that connect to the mentioned servers.

Slow response time of servers, and therefore that of your website, can cause traffic loss and loss in terms of vistors’ interest. Even search engines don’t prefer slow websites. So, if these servers are holding back your website, it’s time to take an action and get rid of modules that call WordPress CDN resources.

    Hi Lalit

    Nice article, i was search for why was making my site so slow. After reading the article I removed Jetpack from the site and it is now very fast. HOWEVER

    I have 20 sites with the same host/server – they ALL have Jetpack installed and only this one site was slow.

    Any ideas why it makes one site slow and not the other 19? I ask as i like Jetpack and would use it if was the same as the 19 fast sites. The slow site is the one linked to in this comment.

    Yes, even if Jetpack have a lot of useful tool, the WP CDN is too slow and sometime JS or Images take up to 14-20 Sec to load.

    A search on ressource with a WP plugin show that Jetpack take %30 of loading ressource.

    I stoped using image hosting also because they drop down the image quality too much, image look ugly and unprofesional.

    I will remove Jetpack from all my website i will look for other solution. The thing that i will regret it’s autopublish to Social website without creating a application.
    But for the rest i will not regret it.

    Thanks for the helpful information this was exactly where i was looking for! Not only my websites are super slow, but also jetpack generates lots of css files and JavaScript.

    To get more speed, I tested different plugins for extra speed and cleaned up css and java script files. I did about 50 Google Speed and Pingdom tests and removed big pictures to get the speed up to 81 percent for my website Google speed test.

    Google webmaster blocked 70 products from my woocommerce store.

    Thanks Guys.

      Hi Mark, I also don’t like JetPack. It is good that you removed the unnecessary CSS and JavaScript files. All the best for your future endeavors!

    Excuse me,is there any other solutions?In my opinion, jetpack is very good.It has markdown,comments,etc.Waiting for your reply.

      WordPress JetPack is a useful plugin, but it refers back to the servers. So, if you’ll use JetPack, your webpage will indeed gets connected to the and that may make your website slow.
