The problem of high packet loss rates experienced by overseas cloud servers may be caused by network issues, which may affect the performance and availability of the server. Here are some common ways to deal with high packet loss rates:

Check your local network: First, make sure your local network is connected properly. Check your local router, modem, and network cable to make sure they are fine. Rebooting these devices from time to time can also help resolve some network issues.

Contact the cloud server provider: If the high packet loss rate is due to a problem with the cloud server provider, contact their technical support team. The vendor can perform network troubleshooting and provide solutions.

Test network connectivity: Use network tools such as ping, traceroute, or mtr to test connectivity and packet loss rates between the server and the local computer. These tools can help determine where in the network path the problem occurs.

Optimize MTU Settings: The maximum transmission unit (MTU) is the maximum size that a packet can be transmitted over the network. If the MTU is incorrectly set, packet fragmentation and packet loss may occur. Try adjusting the MTU Settings of your local computer or server to find the best Settings.

Changing server geographic location: Sometimes, changing server geographic location may improve network performance. Choosing a data center closer to your users may reduce latency and packet loss rates.

Use a CDN: A Content delivery network (CDN) can alleviate packet loss. A CDN distributes content to servers in multiple geographic locations, reducing reliance on a single server.

Monitor network performance: Use monitoring tools to continuously monitor network performance so that problems can be detected and resolved in a timely manner. These tools can help you identify specific time periods and causes of high packet loss rates.

Contact your ISP or network operator: If the high packet loss rate is due to a problem with your ISP or network operator, you may need to contact them to report the problem and request a solution.

Note that dealing with high packet loss rates can take some time and patience, as you may need to work with multiple entities to resolve the issue. Depending on the specific cause of packet loss, different methods may be required to resolve the problem. Therefore, carefully diagnosing the problem and taking appropriate measures is the key to solve the problem of high packet loss rate.
