When using proxy IP, many users will face such a situation: clearly using the same proxy IP, other users can use normally, but they have been failed. This can happen for three reasons:
1. Different network environments:
Each person's network environment is unique and influenced by a variety of factors, such as network service provider, geographic location, quality of network equipment, and network congestion. The combined effect of these factors will have a significant impact on the use of proxy IP.
Firstly, the quality of network communication directly determines the availability and performance of proxy IP. If the delay between the client and the proxy server is high, that is, the delay of data transmission is large, the interaction time of request and response will increase, thus affecting the efficiency of the entire workflow. In addition, the increase in packet loss rate may also lead to incomplete data transmission, resulting in failed requests or incorrect responses, which in turn reduces the success rate.
Secondly, the limitation of network bandwidth will also have an impact on the use of proxy IP. Bandwidth is an important indicator of the network transmission capability. If the bandwidth of the client or proxy server is insufficient, the data transmission speed may be slowed down, the response time may be increased, and the connection may even timeout. This is especially true in the case of highly concurrent requests.
In addition to network communication quality and bandwidth limitations, network congestion is also an important factor affecting the success rate of proxy IP. In the peak period of the network, the centralized access of network users may lead to network congestion, which makes the data transmission blocked. In this case, the response speed of the proxy IP may be significantly affected, which in turn affects the success rate.
According to the difference of network environment, users should make comprehensive consideration when choosing proxy IP according to their own network conditions. At the same time, regular network performance test to ensure the stability and speed of the network is also an effective means to ensure the success rate of the proxy IP. If the network latency is high or bandwidth is insufficient, you can switch to another network environment with better stability to improve the success rate and stability of the proxy IP address.
2. Different business needs:
The business needs of different users may involve different websites, different frequency of data collection, and different access modes, resulting in different ways and requirements for proxy IP.
First, for some services, each proxy IP may need to handle fewer concurrent requests to meet the demand. These services may mainly involve some simple data acquisition tasks, or the frequency of visits to the target website is low and does not require a large number of proxy IP concurrent support. In this case, the proxy IP has a higher success rate because the proxy server can handle fewer requests more easily.
However, for some services that require a large number of concurrent requests, the success rate of proxy IP can be challenging. When concurrent requests are too large, the proxy server may experience a performance bottleneck, resulting in slow response or even timeout of the proxy IP address. In this case, even if the same proxy IP is used, the success rate will vary significantly depending on the number of concurrent requests.
Secondly, different target websites may have different anti-crawling strategies, so it is necessary to select appropriate proxy IP, otherwise the success rate will be affected. Some websites may block frequent requests or manual intervention, so it is necessary to choose a proxy IP with high stability and low risk of IP blocking. Some websites may have no restrictions on proxy IP, and use ordinary proxy IP to meet the needs.
In view of different service requirements, users should select an appropriate proxy IP service provider based on their own service characteristics and reasonably plan proxy IP usage policies. For services with a large number of concurrent requests, you can increase the number of proxy IP addresses or select a proxy server with stronger performance to improve the success rate. At the same time, periodically checking the stability and availability of proxy IP addresses, and timely replacement of unstable or blocked proxy IP addresses are also key steps to ensure success rates.
3. Different code implementations:
Different code implementations of the same requirements can also lead to differences in success rates. The quality and efficiency of the code is very important in the use of proxy IP. Some simple and efficient code can improve the utilization rate and success rate of proxy IP, while long and inefficient code may lead to waste of proxy IP and reduce the success rate.
When using proxy IP, users should choose proxy IP reasonably according to their own network environment and business requirements, and write efficient code to improve the success rate of proxy IP. At the same time, periodically checking the availability and performance of proxy IP addresses, and timely updating or replacing unavailable proxy IP addresses are also key measures to maintain a stable success rate.
