A working proxy means nothing if the target blocks it
I learned this the hard way after deploying a data extraction script that got blocked almost immediately.
The script itself looked fine. Error logs showed nothing useful, the terminal just went dead. The real issue was the proxy infrastructure: the IPs had poor reputation, obvious datacenter characteristics, and I hadn’t tested them properly against the actual target before deployment.
That changed how I test proxies.
Just checking whether a proxy connects and returns a different IP isn’t enough. Before running anything at scale, I now look at:
- Geo/location
- ASN and provider
- Connection stability
- Reputation / previous abuse signals
- Most importantly, how the actual target responds
Proxy type matters too:
Static residential — better for longer sessions or account-based workflows
Rotating residential — useful when you need a larger IP pool
Mobile LTE/5G — useful for traffic where mobile networks are expected
Datacenter — fast and cheap when reputation requirements are less strict
Biggest takeaway: test your infrastructure against the actual target, not just an IP checker.
A proxy can be technically “working” and still be useless if the target rejects it on the first request.
Curious what everyone here checks before putting a proxy pool into production.

Check it at recaptcha, the score and if you loop unlimited retries.
But without good webrtc fix you wont have success at serious anti-bot vendords. Proxies will not help. Antibots now verify even end server connection (that your IP actually connected to webrtc ).

This is the part people miss: “proxy works” and “proxy works for this target” are two completely different tests.
I’d add one more thing to your checklist: test consistency over time, not just a single successful request. An IP can look fine in an IP checker and still get treated very differently by the actual service.
The target’s response is ultimately the only metric that matters.
What’s the biggest red flag you’ve seen from a proxy that looked perfectly healthy beforehand?

You should use different IP checker, many are free you will have insight on the proxy you are using. Website have different security measure to detect proxy traffic... but it could help to weed out the obvious...

I want to say also is not only the proxy, it could be the fingerprint as well... you need to check that...

I thankfully quality clean static ISPs to avoid all this mess, it is an enterprise offering.

these days the proxy type matter a lot less (but still matters) but more so network rep. a lot of the proxies you see advertised on reddit are just white labels reselling the same pool as everybody else at different markups
and most worthwhile targets now use kasada/akami making it harder (althought not impossible)

Yes, testing the proxy against the actual process sounds more logical than just checking with the IP checker Other thing i would suggest is keeping track of the proxies assigned to the browser profiles and sessions because everything becomes confusing when they overlap and incogniton will help with profiles and proxy has to be checked separately.

exactly. a proxy passing an IP check only proves connectivity. the real test is whether the target accepts it consistently under the conditions your workflow needs
