Many of them are only connected by placing two dedicated lines in one location.
It’s not necessarily true that one is in the north and the other is in the south.
Of course, if it is only a site that provides content, there is no problem with this placement. Generally, it is enough to upload content at the same time as required, but applications that have more data access and require strict synchronization cannot do this.

You only need to configure the DNS server,
If the domain name is abc.pcfun.com.cn,
One of them is the main server (202.96.1.x),
The other is a secondary server (202.96.2.y),
Then DNS is configured like this:
Domain: pcfun.com.cn
Host ip
abc 202.96.1.x
abc 202.96.2.y
When the customer enters abc.pcfun.com.cn
DNS first find the 202.96.1.x host
If there is no response, it will find the 202.96.2.y host
