@m0xee @urlyman does HTTP/3 have back off logic built in? A big part of TCP is making sure that normal clients don’t cause a storm when packets are being dropped

TBH, I'm not knowledgeable enough myself about how QUIC, which HTTP/3 is based on, handles that. To me the idea of introducing congestion control into application level (and the implied added complexity of client implementation) seem bad enough, but you might be right, there might be even more to it than that.

Maybe network engineers who had to deal with it in practice can shed some light. My "solution" is disabling it in clients where it is optional (it is in Firefox) and building software such as curl without support for it 😅

@m0xee @urlyman it looks like quic and http/3 have congestion control RFC’s. I totally agree with you wrt doing this at the app layer.
