How to improve the network environment of the website?

problem description

there are times when ping is blocked and network requests are timed out in some areas of the website. There is a chance in any region, and the frequency is not low or high. Excuse me, how can this situation be improved? I don"t have a clue.

Environmental background

Host is a stand-alone instance of Aliyun in South China. I have tried to add cdn or something, but it is of little use, and I feel that the crux of the problem is not this. It may be related to the distributed architecture of multi-host and multi-region.

Please don"t hesitate to give us your advice

it is still a bit difficult for a single machine to achieve stable access to provinces and cities across the country. If you want to achieve this, it is best to rely on multiple servers for distributed access. If you can only use a stand-alone machine, it is best to move the server to a heavily visited area.

so that nothing can be seen.
first improve the monitoring of your own resources, such as network, disk, CPU status, database, etc., at the same time.
then external monitoring, DNS,HTTP (s) plus.
finally, unify the analysis from different dimensions (time, operator, region).
