Using CDN
The Kendo UI CDN is hosted on the Amazon CloudFront.
Only the official Kendo UI releases and serviced packs are uploaded to the CDN. Internal builds are not available on CDN. To access the Kendo UI CDN services, you can use either the HTTP or the HTTPS protocol. Use any of the following CDN services:
kendo.cdn.telerik.com-
cdn.kendostatic.com(a cookieless CDN service)
Using the HTTP Protocol
The minified versions of all JavaScript files are available at the following locations:
https://kendo.cdn.telerik.com/2022.1.119/js/FILENAME.min.jshttps://kendo.cdn.telerik.com/2022.1.119/styles/FILENAME.min.css
For example, the 2022.1.119 version can be loaded from the following locations:
https://kendo.cdn.telerik.com/2022.1.119/js/kendo.all.min.jshttps://kendo.cdn.telerik.com/2022.1.119/styles/kendo.common.min.css
The minified Kendo UI scripts are available as of the Kendo UI Q1 2014 SP1 release. To load the scripts, use the https://kendo.cdn.telerik.com/2022.1.119/js/kendo.ui.core.min.js URL.
Using the HTTPS Protocol
The https://da7xgjtj801h2.cloudfront.net/ URL remains active but is no longer recommended for new projects.
To access the Kendo UI CDN service through the HTTPS protocol, use the same host name from the previous section and replace the scheme (protocol) with https—for example, https://kendo.cdn.telerik.com/2022.1.119/js/kendo.all.min.js.
Troubleshooting
This section provides solutions for common issues you might encounter while using the Kendo UI CDN services.
General disruption and connection issues occur
Description Although the Amazon CloudFront service provides a reliable level of uptime support, you might encounter disruption or connection issues. After you check the status of the systems at http://status.aws.amazon.com/, the CDN status is reported as healthy and operates normally.
Cause You might be experiencing Internet, network connectivity, or DNS problems. It is also possible that firewalls, antivirus, or other security software incorrectly filters out the CDN scripts or modifies (breaks) them on the fly.
Solution Contact your system administrator because remote investigation of connection problems is outside the scope of the Kendo UI Support Team.
It is not possible to refer Kendo UI internal builds from CDN
Cause The internal Kendo UI builds are not uploaded to CDN because they are intended only for clients with a commercial license. Only major Kendo UI releases and service packs are available on CDN.
Solution For internal builds, use private CDN services. It is recommended that you implement a local fallback when you use any kind of CDN. For more information, refer to Scott Hanselman's blog post Fallback from CDN to Local Scripts.
