The Internet Society tracks internet health, publishing data on IPv6 adoption, HTTP/3, DNS traffic, shutdowns, and consolidation.
HN links it for IPv6 adoption figures and its shutdown tracker, though one commenter notes China's low reading likely reflects Great Firewall blocking.
> Wasn't performance the whole point behind HTTP3?
Faster, more secure, and more reliable, yes. The numbers in this article looks terrible, but real-world testing¹ shows that real-world HTTP/3 performance is quite good, even though implementations are relatively young.
"…we saw substantially higher throughput on HTTP/3 compared to HTTP/2. For example, we saw about 69% of HTTP/3 connections reach a throughput of 5 Mbps or more […] compared to only 56% of HTTP/2 connections. In practice, this means that the video streams will be of a higher visual quality, and/or have fewer stalls over HTTP/3."

Yeah and this distinction explains the fact that because China's Great Firewall blocks Google, this website shows 4.66% adoption as a reflection of that. I think China's IPv6 support rate is actually much higher than that, maybe a little over 50% because of its central initiative to increase IPv6 adoption?
EDIT: Apparently it's 77% https://pulse.internetsociety.org/en/news/2026/01/china-hits-865m-ipv6-users/
Can we cut this shit out? It's 2022, IPv6 has worked fine for decades, and Google is seeing 40% IPv6 usage on their services:

When you're at a protest and the government shuts off the internet in response to the protest. It's happening right now in Togo, has been for ten days (https://pulse.internetsociety.org/en/shutdowns/).
Based on current trends, probably closer to 2024/25 for the global 50% mark.
