Content distribution network (Content Delivery Network, referred to as CDN) is a distributed network, which is established and covered on the bearer network, and is composed of server groups of edge nodes distributed in different areas. CDN shares the pressure on the origin server, avoids network congestion, ensures that the distribution of website content is accelerated in different regions and different scenarios, and improves the speed of resource access. Many users will encounter the problem of how to make effective use of CDN in the process of actual use of CDN. Today, the editor will briefly introduce the problem of CDN acceleration.

How do I check to see if the website is cdn accelerated? Now generally better sites will turn on CDN acceleration to improve user access speed, many webmasters want to know how to look at the site whether the CDN service is open.

To see whether a website opens CDN, the method is very simple, as long as you ping the URL in different regions. For example, the IP address you get in Beijing ping is one, but the IP you get from the same ping address in Zhejiang is another. If you ping the same URL in different regions like this, and get different IP addresses, then you can judge that the site has opened CDN acceleration.

If the website does not have CDN enabled, the Ping URL in different regions is the real address of the website server. If CDN acceleration is enabled, the content of the website will be cached to the nearest server in each region, so accessing IP will change. According to this principle, it is easy to judge whether the website has CDN enabled.

How can one computer ping multiple regions? If you are not afraid of trouble, you can ask your QQ friends from different regions to give you a ping test, and then tell you the IP result. This is the stupidest way.

A method for testing the national access speed of a website

Use online tools to test whether the site is on CDN, and you can test the speed and IP address of accessing the site in different parts of the country. Through these tools, you can not only easily find out whether the website has CDN enabled, but also test the access speed in different parts of the country.

Maybe ordinary users don't care about website speed measurement, but if you sometimes encounter a website that can't be opened but can be opened in other areas, you can try the above method to see if it is caused by the slow access speed in your area.

The above is an introduction to how to check to see if the website is cdn accelerated. Virtual hosts can enjoy Baidu's massive CDN node resources free of charge, rich node resources, covering the whole world, and provide acceleration services for a large number of users with unlimited traffic.
