We often encounter the case of the US server IP. In fact, the service providers rarely take the initiative to seal the user IP. It is very likely that the operator has sealed your IP or your IP is blocked.

　　Generally there are the following points:

　　1. Violation of local laws and regulations

　　This type of American server IP is blocked, and the service provider is helpless. The service provider collects the cost of users, but does not mean that users can do whatever they want on the server and do something that does not comply with laws and regulations, especially in the mainland and the United States. Internet laws and regulations are becoming more and more complete. In the case of increasingly stringent cases, users must comply with the agreement with service providers, that is, the service provider's "Service Terms". Users should carefully read this part of the terms before purchasing the server.

　　The terms of most service providers are to add some of their own detailed regulations on the basis of laws and regulations. Of course, it is not ruled out that a few service providers do not do things in accordance with laws and regulations. This type of service provider focuses on money. Once the user's US server has violated the law, it will not remind the user and make limits in a timely manner. After the computer room is detected or reported, the machine room and the operator take the measures to seal the IP. It is not recommended that users cooperate with such service providers.

　　Second, peers or hackers invading servers

　　Traveling or hackers obtain the US server vulnerabilities through some means, and then defeat the user's own system or set the server with some parameters. The server runs abnormal. The purpose of being blocked by a third party.

　　As a service provider, we will do our best to do the defense system of the American server, achieve the least loopholes, and do a good job of monitoring systems. We also recommend that users should configure the parameters of the server, close unnecessary ports and services, repairs system loopholes in time, and so on.

　　Third, encounter traffic attack

　　It is the most common to be blocked because of traffic attacks. For this situation, users are unjustly unjustly. The user IP of the service provider is also helpless. For traffic attacks, ordinary American computer rooms are unable to resist at all, such as DDOS attacks and CC attacks. Once ordinary computer rooms encounter this type of attack, the entire machine room network will appear unstable. Server overload work.

　　In this case, the service provider can only seal the corresponding IP by being attacked, so that the traffic attack cannot continue to attack, but this also causes the user IP to be blocked. If the user server has a traffic attack for a long time, we recommend renting a high -defense server. This is a server specializing in defensive traffic attacks. If the user's IP, during the period, what loss or impact on the user will also hope that users can contain more.
