The region where the US server is located has rich IP resources, advanced server equipment and technology, and the US server provided by it has high cost performance. Users who rent American servers also have IP blocked. When American servers are blocked, they can't access American servers in other regions. Here is a summary of some common situations that can easily lead to IP blocking of American servers. I hope to help you!

1、 Encounter network attack

There are many types of attacks in the current Internet environment, and the degree of network attacks varies. When a U.S. server encounters a network attack and is detected by the computer room where the U.S. server is located, the IP address of the U.S. server will be immediately banned and the U.S. server will be disconnected. DDOS attacks in Internet attacks are common network attacks. This kind of attack will cause sudden invalid input/output or slow requests, which will increase the demand of American servers beyond the bandwidth and lead to the downtime of American servers. After the US server strike, the websites hosted by the US server cannot be accessed normally, and even the attack may affect the operation of other machines in the US computer room. Therefore, once the network attack is detected by the computer room, the IP will be immediately blocked.

Network attacks often achieve the purpose of attack by attacking domain names or malicious parsing. In many cases, it is necessary to find out the cause of the attack by quickly eliminating the attack, such as opening the protective wall, traffic cleaning, etc.

2、 Malicious attack invasion

When hackers invade, they use the US host as a broiler to scan other servers maliciously, which will also be recognized by the US computer room and then actively intercept and block the IP.

3、 Violation of local laws and regulations

Even though American servers have relatively loose restrictions on content, there are still some laws and regulations that restrict the network environment. For example, intellectual property infringement, bad information and phishing websites are not allowed in the United States. The website will also be banned by the computer room after being reported or discovered by the relevant department.

In this case, it is best to examine the website's business content. If it is caused by malicious intrusion, you can appeal to the operator of the computer room where the server is located in the United States. However, if it is really involved in violation of laws and regulations, the IP is not allowed to be unsealed.

4、 US server network resource overload

When the input/output data borne by American servers is too large, which far exceeds the bandwidth resources of American servers, it will lead to the closure of IP by American server suppliers. Although most users rent US servers with unlimited traffic/limited bandwidth, abnormal traffic usage will also encounter banned IP processing, which often occurs in the use of US cloud servers and US vps servers.

In case of the overload of US server network resources, the bandwidth can be upgraded in a timely manner, and the relevant problems can be solved before being unsealed.

The above are the four common reasons that lead to the closure of the IP address of the US server. Before renting the US server, it is better to carefully understand the service terms of the US server supplier, use the US server correctly and safely after renting, carry out daily security maintenance on the US server, comply with the relevant laws and regulations of the local Internet, avoid hacker intrusion, and effectively communicate with the US server supplier, Jointly maintain the security of American servers.
