There may be two reasons:

1. IP is blocked-the server IP is blocked in China and cannot be accessed normally.

2. The service provider changes the server. The second item, that is, the replacement of servers by service providers, is relatively rare. Generally speaking, this situation is often seen in Internet companies that operate the server on a personal basis, or in a network company that has not been operating overseas hosts for long. For the first reason, it is something that happens to almost all overseas service providers. Overseas space operation is by no means different from the domestic virtual hosting mode, without considerable overseas host operation experience, it is absolutely difficult to do a good job of overseas hosting services. The IP here is limited to the scope of Chinese mainland, that is, only Chinese mainland is blocked, and visits outside the mainland are completely normal.

So why are they blocked so often? The main reason is that service providers lack content management and the Internet environment on the mainland is basically clean, and a large number of illegal websites have no way out in China, so they have to find another shortcut and place their websites outside China.

So a large number of illegal personal websites, such as porn, gambling, fraud, Trojans, turn to overseas hosts. Those who understand English will find large overseas service providers, but there is still a problem: overseas local service providers are unable to run their websites, mainly due to garbled codes and abnormal functions, which is caused by their character set.

In this way, 90% of domestic illegal website operators will consult overseas hosting operators in China, but the problem is that almost all operators do not regularly check and manage the content of their websites, let alone use illegal content interception systems.
