Falsehoods programmers believe about TCP (lwn.net)
FWIW, I dropped NetworkManager years ago for `wpa_supplicant`-based management because I had flaky wireless situations (thick concrete walls in the dorms, roaming across campus, etc.) and any whiff of packet loss would announce to the whole machine "no network" and apps would start to freak out and react. However, it was likely to be back Real Soon™ and normal TCP recovery would make it "transparent" (if with a spike in latency).

Bringing insights into TCP resets and timeouts to Cloudflare Radar (cloudflare.com)
Cloudflare handles over 60 million HTTP requests per second globally, with approximately 70% received over TCP connections (the remaining are QUIC/UDP). Ideally, every new TCP connection to Cloudflare would carry at least one request that results in a successful data exchange, but that is far from the truth.
