MASTER_SITES points to yt-dl.org which has both A and AAAA RRs:
$ host yt-dl.org
yt-dl.org has address 188.8.131.52
yt-dl.org has IPv6 address 2001:1a50:11:0:5f:8f:acaa:177
Dual-stack nodes would fallback to 184.108.40.206 if AAAA failed,
but IPv6-only nodes (with DNS64 or not) can only try AAAA, which
is unreachable from at least AS8359 and AS207996:

Upstream was notified via e-mail to hostmaster from SOA of zone in April,
no response and no issue resolution since then.
I think switching to USE_GITHUB (DNS64) or mirroring distfile on FreeBSD cluster
would fix this, until the issue is fixed by yt-dl.org hostmaster.

Patch attached with commit message ("git am").
I used upstream provided tarball instead, as in https://cgit.freebsd.org/ports/commit/?id=29e87cd021e8fb0ef77948bc5e049f1283e2a493
Stick do DISTVERSION everywhere rather than mixing PORT and DISTVERSION and why not keep main site as fallback?

> why not keep main site as fallback?
GH likely has better bandwidth and uptime; I don't see the need to keep
yt-dl.org. Hostmaster ignores mail, so if the website is down, it would
likely remain down longer than any possible GH outage. I think it would
not hurt to have yt-dl.org as a fallback, attached v2 after your review.
A better solution would be to mirror the distfile at distcache.FreeBSD.org,
which has AAAA RR without the need of DNS64/NAT64. I think only a committer
can do that.
> Stick do DISTVERSION everywhere rather than mixing PORT and DISTVERSION
Right, I wanted to minimize the amount of change, so a maintainer is more
likely to approve the patch. V2 changes more as you suggested.
Thanks for review.
yt-dl.org link stil uses PORTVERSION, as a workaround for those who don't want to fetch it manually for now at least might be www/yt-dlp which is a compatible fork (uses github.com)
(In reply to Daniel Engberg from comment #4)
Well, seems like I wasn't paying much attention and just copied it as-is... I was distracted with something else yesterday; this is trivial enough to change if someone commits it, sorry for that.

www/youtube_dl: Add Github to MASTER_SITES.
The original site is unreachable from IPv6-only networks.
While there, switch to using DISTVERSION.
