Is it just me or the graph at the end of the article is not really showing rising adoption in general. It basically shows a couple of spikes - each corresponding to some big company switching their edge servers to HTTP/3 like Alphabet, Meta, Cloudflare. There is no gradual increase.
Furthermore, I don't see easy solutions yet for some problems with QUIC - for example browsers still try to establish a TCP connection first unless they know for sure the server supports QUIC. Proxy support for HTTP/3 is still in its infancy, but for many corporate envuronments it is a hard requirement.
So outside of the biggest websites, which I admit also take up a large chunk of the network traffic, is QUIC really replacing TCP in the general Internet?
