I keep seeing threads about residential vs datacenter for heavy tasks, and everyone seems to miss the middle ground. I've been running ISP proxies for a client's large-scale product data scrape for about 6 months now. The results have been surprisingly consistent. We're pulling around 2-3 million requests per day with a success rate averaging 92-95%, and that's on some aggressive targets known for blocking. The key is that ISP IPs come from actual internet providers, so they look like home users to most sites but they live in datacenters. You get the trust of a residential IP without the insane cost and volatility of a pure residential pool. Our cost per successful request is about 40% lower than when we were on premium rotating residentials. Speed is another win, average response time sits at 1.8 seconds versus the 4-5 seconds we were seeing with mobile or residential rotations. My takeaway? For any automated task where you need volume and reliability more than perfect geo-targeting, ISP proxies are AF. Just make sure your provider isn't just reselling datacenter IPs and calling them ISP. The proof ladder here starts with raw success rate numbers before you even look at speed.
