Github is not available from IPv6

Update:

The old jool.mx is again offered as a fall-back workaround. It should be available both from IPv4 and IPv6.

jool.mx is still a little rough in that it can still take several days to reflect updates, so github.io is still preferred where available. Not really anymore.

Actually, for some reason jool.mx can't be accessed from some parts of the world via IPv6. It seems they have some routing/DNS problem they need to spot. This issue will remain open until it's sorted out.

We're having trouble finding a source from which a failing traceroute can be performed.

Is there somebody out there being affected by this problem? Can somebody please provide an IPv6 traceroute?

Specifically, the problem is the warning being reported here:

http://validador.ipv6.br/index.php?site=www.jool.mx&lang=en
http://ready.chair6.net/?url=www.jool.mx

I have ran some measurements using RIPE Atlas :

https://atlas.ripe.net/measurements/?search=jool.mx&status=&af=&kind=&age=

You can find a ping msm followed by a traceroute from those probes which didn't get a positive outcome from the previous ping.

Sorry, I haven't had time to analyze results yet :-/ Hope to do something more tomorrow.

Thank you!

I can't really do much with the output, but sysadmins report that they're getting different errors and from different sources. Still trying to find a pattern.

This issue is resolved, as GitHub Pages / Fastly has enabled IPv6 for all *.github.io domains.

...................................................................... huh.

I was going to say that it's pretty odd that both validators report roughly the same warnings for both www.jool.mx and nicmx.github.io/Jool, but then I realized that, actually, they also report the same problems for www.google.com.

In fact, out of the three, jool.mx is the one that has the least warnings overall.

I'm really really stumped right now. I wonder if it has always been like this.

Not sure about closing this issue, but at least it's pretty obvious that it no longer deserves the critical tag.

Then again, nobody has ever actually complained about this...

Update: github.io dropped IPv6 support. As a matter of fact, so did github.com, apparently. Since Jool releases are currently hosted on Github, and the Debian package is still queued, Jool is mostly unavailable from plain IPv6 right now. (The possible exceptions are the OpenWRT and openSUSE packages.)

Working...

Though the repository and bug tracker are still unreachable from pure IPv6, the latest tarball is now hosted in jool.mx itself. So, IPv6-only users should be able to reach it.

I will therefore downgrade the severity of this bug.

FWIW I've been logging jobs for a long time through our Enterprise GitHub account for native IPv6 support on all GitHub services. Unfortunately they've never come back with a definitive road map of when and how this will actually occur. Sad times.

I plan to log another in early 2021 to see where they are at.

[ydahhrk]

Well, in truth, I suppose there's no point in keeping this issue open now. This is a Github bug, and hosting the latest release in jool.mx seems to be enough for Jool. And I don't see any other solutions.

Will include this issue in the 4.1.5 release and close it when that's out.

[ydahhrk]

4.1.5 released; closing.
