Distributed Crawler IP Cold Start Scheme: Initial Request Strategy to Avoid Blocking

First, the cold start rollover site: the crawler is still not working on the blocked what to do?

Newbies who have just built a distributed crawler often encounter this kind of embarrassment: before the script has run for half an hour, the target site throws over a 403 blocking alert. It's like just entering a casino and being taken out by the security guards, with all the chips in your hand unused. At this timeProxy IP quality and usageIt directly determines whether or not you can get off to a good start.

The traditional approach is to just take the free agent and tough it out, and the result is:
- Survival rate less than 20% IP pools
- Requesting head fingerprints were accurately identified
- Triggering the trifecta of death for website wind control (blocking IPs, bouncing CAPTCHAs, and returning fake data)

Second, the four strokes of the day: ipipgo real test effective cold start program

Style 1: Agent Pool Warm-up (don't come up here and make a big move)
Newly registered ipipgo accounts don't start crawling yet, use theirIP warm-up interfaceDo three things:
1. Take 5-10 residential IPs for heartbeat detection (each IP sends HEAD requests at 30-second intervals).
2. Mixing IPs from different geographic locations (don't pile on the same server room)
3. Record the first response time for each IP (direct throw if more than 2 seconds)

Style 2: Traffic camouflage should be wild enough (don't be a good boy)

Website risk control is best at catching "perfect requests", so you have to intentionally create some imperfections:
- With ipipgo.Random UA GeneratorMix and match device types (don't clear Chrome)
- Randomized fluctuations in request intervals (between 0.8 and 3.5 seconds)
- More mobile IPs in the early morning hours, more broadband IPs during the day
