Interesting!
So far I've only seen Bright Data (among the large players) offer UDP proxying over QUIC/HTTP3, but that's pretty limiting since less than half of sites have HTTP/3 enabled to begin with.

That's what I thought too, but it's working for me. (I've sent a lot of tickets, maybe they've put our account as something special without telling me, but doubt it.)

Done, emailed! :) Thanks!

Out of the large players I've tested, none actually seem to even support SOCKS5's UDP ASSOCIATE. (I have not tested PingProxies yet.)

I think there's a knowledge gap between the people making the sales landing pages, and the folks who actually run/maintain the proxy servers. There's some large vendors that advertise UDP support (for residential and/or mobile proxies) that I have yet to actually see working.

We (PingProxies) might be the only company to offer H3 to the proxy/QUIC to the target using the CONNECT-UDP method publicly. Although, it is in beta/unstable until I merge my changes into Rust's H3 library.
If you wanna play around with it, email me and I'll get you some credit. I think theres potential for stealth since outdated proxy clients/servers mean automated actors never use H3.
