I been using residential proxies from two different providers for my automation setups but they still die after a few days of heavy use. It used to be more stable. What are you running in 2026 that actually lasts?
A couple of things are worth looking at here: the provider’s infrastructure and the proxy type itself.
Most people focus only on the IP quality, but the proxy manager/gateway infrastructure matters just as much. Even if the IPs are stable, if the provider’s proxy manager gets overloaded you’ll start seeing higher failure rates. For heavy automation setups, the provider needs proper horizontal scaling so their system can handle a huge number of TCP connections without slowing down.
Another thing is request distribution. You can’t realistically push millions of requests through the same proxy endpoint (same IP or session). It doesn’t matter if it’s DC, ISP, or residential — eventually it will fail or get blocked.
Datacenter and ISP proxies usually handle heavy traffic much better because they run on actual servers with stable bandwidth. Residential proxies come from real user devices, so they naturally have lower tolerance for sustained load.
So there’s always a trade-off:
• ISP/DC → higher performance but smaller pools and lower IP quality
• Residential → better IP quality but lower performance and stability
If your setups start dying after a few days of heavy usage, it’s often not just the proxies themselves. Sometimes the provider’s gateway can’t handle the volume, or the traffic isn’t distributed across enough sessions/IPs.
In my experience, stability at scale mostly comes down to infrastructure and how well your traffic is distributed across the pool.
We ran into the same issue before while building proxy infrastructure for ProxyFog. In many cases the problem wasn’t the IPs themselves, but gateway overload or pushing too many requests through the same session.
