IIUC, those numbers could potentially reach ~89% as that's what you achieve using first party apps. Safari routinely performs HTTPS lookups and yet only reaches 40%. The use of old operating systems is probably only part of the reason.

I was mainly thinking about CDNs, whose business offering is to deliver web content as quickly as possible. It's still surprising to me that H3 is a small percentage on many CDNs.

If that was filtered to Meta destinations, perhaps you'd see the 60% figure that Matt sees. The question I'd ask is "so?" Should we care that QUIC isn't racing to the > moon? I care about making the internet work better and be more responsive to users. QUIC is a major improvement in that sense and it's sad to see it being limited to a subset. I'd like to deliver these benefits to more people, more of the time. As a community we can take actions that result in H3 overtaking H2 on the internet. Chris
