For the last seven months, Google has pushed every non-login search from my house network through a captcha; the image captcha is typically five to infinite repetitions. Audio captcha works after a single run-through, except that it is frequently "unavailable" now.

I don't know why. Google won't tell me. They just started doing the same for YouTube: "Please login because we have detected malicious behavior from your network".

I know I'm not DDOSing them; I can see all our network traffic. They're just encouraging me to avoid using them.

You're probably blocking ads or blocking tracking in some fashion and denying them signals their naive models use to evaluate whether you're bot-or-not. It could be somewhat intentional but I'd lean towards it being an edge case they just don't care to address.

It's a big enough edge case that not caring to address it makes it intentional.

In my case, they block me on IPv6 since I use a Hurricane Electric IPv6 tunnel. It certainly used to be the case that my IPv6 connectivity was better and more performant down the tunnel than using my ISPs native IPv6. I have no idea what the situation is today.

My solution was to use a filtering DNS that always returns no AAAA records for domains ending in google.com. This works great and essentially solves the problems. I have to do the same for various netflix domains as well.

I'm dreading having to switch over to native IPv6 -- I don't even know how many /64s will be allocated to me (and how stable they will be).

This could very well be the answer. I'll go check.

That's it. Google now automatically distrusts my HE tunnel. No idea why.

The joy of CGNAT.

Well maybe someone in your network or subnet is doing some abuse.

I feel this. Recently _some_ company, I have no idea which, has decided my IP is malicious and refuses to serve my requests. This has effectively banned me from a few websites, including a government service I pay taxes for.
