How to solve the websites of the cloud host server, check the speed of local visits to various domain names, and confirm whether there are problems with local networks. Check the network link, confirm whether there are cases of packet loss or high delay, check the analysis of DNS, check whether the problem caused by DNS resolution, check whether the use of cloud servers is abnormal, such as CPU, memory, and bandwidth. Essence

　　1. Check the local client

　　Local client access the network diagnostic analysis system to test the speed of local visits to various domain names. According to the test results, confirm whether the local network has problems.

　　2. Check the network link

　　Local client ping cloud server public network IP to confirm whether there are packet loss or high delay.

　　3. View the analysis of DNS

　　Use the DIG/NSLookup command to check the analysis of DNS to check whether the problem caused by DNS analysis. You can also use the public network IP access to the corresponding page to check whether the problem of DNS causes access to access.

　　4. Check the server to use

　　If the cloud server is excessively used in CPU/memory, or there is a situation where the bandwidth is too high, it is determined whether the resource consumption caused by the server load is increased. Excessive CPU or memory usage rate can easily cause the service response speed to slow down, and the server login is not up. If there are too many website traffic or resources, it is recommended to optimize business procedures or upgrade Hong Kong server configuration. You can also share the pressure of the existing server by buying a new server.
