Your proxies are up. The exit IPs check out clean. Then a lander won't open in the target region, a cloak returns the wrong page, or a scraper starts throwing random host errors. Most people blame the

So yeah, this troubleshooting guide absolutely slaps - DNS is basically where all your silent failures go to hide, and the author nailed it by splitting out proxy testing from client-side testing. That APNIC stat about AAAA failures hitting 64.2%, that's the kind of we need to change how we do this data point that actually moves the needle operationally. To really level this up tho, you'd want some solid workarounds for IPv6 headaches like just yeet-ing those AAAA queries and going A-only, a breakdown of how EDNS Client Subnet messes with geo-targeting, and a heads-up that DoH straight-up bypasses proxy DNS in antidetect profiles. One more thing, google's sitting on like 68-70% of the open resolver game, so saying nearly 50% is kinda lowballing it

Really appreciate this especially the EDNS Client Subnet point, that's a gap worth addressing directly since it's exactly the kind of thing that silently breaks geo-targeting even when everything else in the proxy chain looks correct on paper. The DoH-bypasses-proxy-DNS issue is a great catch too - that's a real blind spot for antidetect setups specifically. A profile can look fully proxied at the network layer while DNS resolution quietly leaks straight through DoH, outside that path entirely. On the A-only/skip-AAAA workaround - agreed it's a fair pragmatic fix for most proxy-routed setups today, worth adding as a concrete option even though it trades off some future-proofing as IPv6 adoption keeps climbing. Good push on the resolver-share number too will go back and check the source on that and get it corrected if it's undercounting. Appreciate you actually digging into the numbers instead of skimming past them. Might turn the ECS + DoH points into a proper follow-up piece on their own, honestly — they're meaty enough to deserve more than a paragraph each here. Thanks for the genuinely useful read.
