Today, I will talk to you about the reasons for the failure of ping CVM. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.

What is the reason why the ping CVM failed? The ping value represents the response time of the network and is one of the criteria to measure the transmission speed and stability of the CVM. There are many reasons for the failure or instability of CVM ping.

Resource overload

When users visit the website, if the server already has a large number of programs running in the background, and occupies a lot of space, so that the resources are overloaded, then the loading speed of the website will naturally slow down, or even may not be able to open.

Generally speaking, we recommend that you keep the remaining resources at about 40%. If it has been exceeded or there is little left, you need to check the CVM, delete useless programs and files, and be sure to prohibit programs that are not frequently used from booting.

Firewall restriction

Frequent use of firewalls can also lead to unstable server Ping values and slow access speed. It is recommended that one of the most powerful and comprehensive firewalls be retained, even if there are many places that cannot be defended.

Server performance

If the capacity of the CVM is not large, the bandwidth is insufficient, and the performance is not high, when a large number of users visit the website at the same time during peak hours, it may not be able to carry so many requests, resulting in slower speed or lack of direct connection. This situation is usually not a problem for access at other times, but it is still recommended to upgrade or replace the server.

Virus invasion

This is a phenomenon caused by external factors, such as virus intrusion, DOOS attacks, etc., resulting in server anomalies, the ping value will naturally become unstable. Defense and clean-up scanning of CVM should be carried out on a daily basis.

It is a well-known cloud computing service provider in China, providing secure, stable, efficient and convenient cloud servers, 24-hour service for after-sales technicians, and product purchase link h

After reading the above, do you have any further understanding of the reason for the failure of ping CVM? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
