What is CDN

What is a CDN?

 Note: View Wurk Managed WordPress hosting plans

A content delivery network (CDN) is a network of servers that deliver content. The purpose of the CDN is to cache and more quickly serve static content based on the geographical location between the origin server (the server your site is hosted on) and the user making the request. This means when someone in Japan visits your website hosted in the United States, it will load just as fast as a website hosted in Japan.

The benefits of using a CDN are:

• Improved content availability and redundancy - High volume traffic or hardware failures can cause downtime for your website; a CDN distributes the load so your site can handle more traffic and endure hardware failure better than a single origin server.
• Improved load times - Users are served content from a point of presence (PoP) geographically closer to them than the origin server, which means faster load times for your website.
• Increased security - A CDN can increase security by mitigating distributed denial-of-service (DDoS) attacks, preventing vulnerability hacks, and stopping brute force attempts against your website login pages and more.

Not all CDNs are the same. There are both static asset cache CDNs and full-page cache CDNs. The difference is the amount of server load you pass through the distributed network of servers around the world. Full page caching works to improve the load on your server by distributing not just your static assets, but the blocks of code and information from the database for your site.

CDN options bundled with Managed WordPress: 

• An updated version of the bundled CDN offering for Managed WordPress sites, that includes full-page cache technology, is now available for eligible customers. This new CDN solution is an industry-leading product that can reach 95% of the world's population within 50 ms. Included with this new CDN is a Web Application Firewall (WAF) service that will keep your site more secure against potential bad actors.
• For sites ineligible for full-page cache, the static asset cache will remain in effect.

For sites that register their domain with Wurk and have the CDN enabled within their Managed WordPress settings, the new CDN with improved optimization and security features will automatically take effect.

CDN image indexing and Yoast SEO

 Note: Before making any custom changes to your WordPress theme, you should add a child theme, to avoid losing your changes the next time you update the theme.

To ensure images are being indexed properly by Google Search Console when using the Yoast SEO plugin and a CDN, you should add a small snippet of code to the top of the functions. php file. This code will allow Yoast SEO to properly generate the sitemap for your WordPress website.

1. Connect to your site with File Manager or FTP.
2. Go to the wp-content/themes directory.
3. In the folder with your active theme, find and open the functions.php file.
4. In the functions.php file add this snippet of code to the top of the file and replace example.com with your own domain name.

5.    function wpseo_cdn_filter($uri) {return str_replace  ('https://www.example.com','https://secureservercdn.net/example.com/, $uri);}

6.    add_filter( 'wpseo_xml_sitemap_img_src', 'wpseo_cdn_filter' );    

7. Save the changes.
8. Sign in to WordPress
9. On the left-side menu, select Yoast SEO and then select Settings.
10. Select Site features and scroll down to the APIs section.
11. Find the XML sitemaps feature and disable it.
12. Clear the cache and enable the sitemap feature again - that will force the sitemap to rebuild.

The sitemap will now use the CDN URL to reference the images. After this change it could take several days for the images to re-index in your Google Search Console.

Remove my site

Note: View Wurk Managed WordPress hosting plans.

If you no longer want to use a site or want to start over, you can remove it from your Managed WordPress plan.

 Note: Removing a Managed WordPress site with a domain attached will automatically park that domain until you use it again.

 Warning: Removing a site permanently deletes all content from your Managed WordPress website. You should only remove a website if you're okay rebuilding the website from the beginning.

1. Go to your Wurk product page.

2. In your My Products page, next to Managed WordPress, select Manage All.
   
   
3. For the website you want to remove, select Remove from the  menu.
   
   
4. Type Remove, then select Remove.

Your site has been removed! Don't worry, this doesn't cancel the Managed WordPress plan, just the site. You can add a site when you're ready to start over.
