[metrics-team] why a working exit detection became more relevant today

[nusenu]

Hi,

as you have probably noticed, Cloudflare deployed opportunistic .onions [1] for _all_
domains using Cloudflare's free and pro service.

They serve alt-svc HTTP headers to tor browsers coming from tor exit IPs to steer them
towards .onions, so their ability to detect tor exit IPs has a direct influence
on the success-rate of this setup.

According to a user on tor-talk [2] the alt-svc header is often missing when
the tor exit speaks IPv6.

Maybe this could be a motivation to address:
https://trac.torproject.org/projects/tor/ticket/24034
(I'm pointing to the duplicate because it has more content than the other one)

kind regards,
nusenu

tbh: I still like the fact that not all IPv6 exits are not enumerated yet because
it makes the web for tor users a tiny bit more accessible.
