Crawler long-lasting stable agent pool | 7 × 24 hours automatic maintenance updates

Real-world scenario: why is your crawler always blocked?

Friends who have done data crawling have encountered this situation: a script debugged at 3:00 a.m. receives a blocking notice from the target site the next morning. This is not a code problem, but your network fingerprints are recognized - just like the same face repeatedly swiped into the company, the security guard will sooner or later stop and question.

Last year, we helped an e-commerce customer to capture public price data, the first three days can be normal collection, the fourth day suddenly received 503 error. After troubleshooting, we found that the other website had setSingle IP access frequency limitThis is when you need to use a proxy IP to give the crawler a "new face" and theResidential Proxy IP for ipipgoIt happens to simulate the real user network environment.

The three core elements of proxy pool building

A long-lasting and stable proxy pool is not simply a stack of IP addresses; it requires three key components:

1. Quality IP sources:Choose someone like ipipgo who offersReal Residential IPservice provider, their IP pool covers 240+ countries and regions, each IP comes from home broadband and is harder to recognize than server room IPs

2. Smart scheduler:Automatically detect IP availability and immediately switch to a new node when it encounters a failed IP. It is recommended to use multi-threaded parallel detection, and IPs with a response time of more than 3 seconds are directly eliminated.

3. Traffic camouflage:Set random request intervals (0.5-3 seconds) to simulate manual trajectories. In conjunction with ipipgo'sDynamic IP RotationFunction to automatically switch to a different exit IP for each request

Automated Maintenance Practical Tips

Here's a maintenance solution we're using internally (Python example):

 Automatically update the 30%IP pool every morning
def ip_refresh():
    old_ips = get_expiring_ips() get expiring IPs
    new_ips = ipipgo.get_ips(len(old_ips)//3) get new IPs
    update_ip_pool(old_ips, new_ips) hot update proxy pool

The key point is this:

- Maintenance time is selected during the low peak period of website access (02:00-05:00)
- Each time the replacement does not exceed 1/3 of the total pool volume, to ensure the stability of the IP pool
- Using ipipgo'spay-per-use interfaceDynamic IP acquisition to avoid resource wastage

A Guide to Avoiding the Pit: Mistakes 90%'s Make

Seen too many people make proxy pools like this:

❌ Use of free proxy IPs (less than 20% survival rate)
❌ Successive intensive requests from the same IP
❌ HTTP/Socks protocol mixing without rules
❌ Ignoring DNS leaks

The correct approach is:
1. Selection supportAll-Agreement Agentsservices (ipipgo supports HTTP/HTTPS/Socks5)
2. Configure the X-Forwarded-For parameter in the request header
3. Setting up DNS resolution at the proxy server level to avoid exposing the real server location

Frequently Asked Questions

Q: What should I do if the proxy IP expires after a few minutes of use?
A: This is common with low quality proxy services. It is recommended to use ipipgo'sHigh Stash Residential IPThe average availability of a single IP is more than 6 hours, and a real-time availability detection interface is provided.

Q: How can I tell if my IP is blocked by a website?
A: Observe the three signals:
1. Continuous occurrence of 403/503 status codes
2. Sudden increase in the percentage of pages receiving CAPTCHAs
3. Time spent on the same request is more than three times longer than usual

Q: How to choose between dynamic IP and static IP?
A: High-frequency collection with dynamic IP (automatic switching anti-blocking), need to maintain the session of the scene (such as the login state) with a static IP. ipipgo two types are supported, and can be mixed use.

Maintaining a proxy pool is like raising fish, you need to have a good water source (quality proxy IPs) and you also need to be able to change the water regularly (automated maintenance). Choosing a professional proxy service provider like ipipgo is equivalent to directly obtaining a source of living water, and the rest is to design your "circulation and filtration system". Remember, stable data collection is never about the number of IPs, but about who can maximize the use of limited resources.
