Guide to Fix Site Slow Due to Blocked MaxCDN URL by MCMC of Font Awesome of Wordpress
Update as of 10th Aug 2022:
We've also noticed that polyfill.io is also being blocked by MCMC now. Detected blocked remote resources by MCMC as of today is maxcdn.bootstrapcdn.com ** and **polyfill.io
Recently, Malaysia MCMC has blocked the following hostname which caused slow issue for any WordPress website that uses/loaded Font Awesome on the following remote sources:
This issue has caused slow website loading, when the website is loaded from Malaysia ISPs i.e Unifi, Digi, Maxis, Celcom, etc.
There are 2 methods to resolve this.
Tutorial for hosting Font Awesome in your own hosting can be found here: https://fontawesome.com/v5.15/how-to-use/on-the-web/setup/hosting-font-awesome-yourself
This is the easier method as the first method require script/coding update, which lots of Wordpress users may not want/know how to go about. Font Awesome are commonly bundled with some themes/plugins and most likely are not being used. So it is safe to unload them. You can easily unload Font Awesome via a plugin such as https://wordpress.org/plugins/wp-asset-clean-up/
- Login to Wordpress Admin Dashboard
- Go to Plugins ** >> **Add New
- Search , install ** and **activate ** the plugin **Asset CleanUp: Page Speed Booster
- Go to Settings >> Asset Cleanup to open the plugin settings
- Click on the tab CSS & JS Manager and wait for it to fully load
- Use your browser search to search for CSS resource begins with https://maxcdn.bootstrapcdn.com/ and tick on Unload site-wide * everywhere checkbox. This is to unload the said blocked resources site-wide
- Lastly, click the Update button and clear your site cache via the cache plugin that you are using
