For what it's worth, on Spectrum Residential here in LAX and I
can reach ip6echo.net and Google's public ipv6.google.com sites
via residential service... I have my own modems and routers,
which may make the difference in my case... Spectrum does indicate
that IPv6 my need to be enabled on their routers...

I normally use the Google IPv6 site for such tests to avoid
irritating private hosts, so a big thanks to Brandon for
offering that alternative!

If it is helpful, I am on Spectrum in Ohio and I can reach that address from my IPv6 test system. This is on a commercial account with a provider assigned network. My system is at ip6echo.net. You are welcome to ping and traceroute to it if that is helpful to you. A friend CANNOT get to that address from a Spectrum residential account also in my area.

Hey all, I'm posting this here in hopes of getting the attention of someone that can get this issue resolved, or at least an internal ticket filed. I've tried the customer-facing tech support and not been able to get such a thing done. In short, from within Spectrum's US IPv6 network (verified in both North Carolina and Ohio), dfw.source.kernel.org (2604:1380:4641:c500::1) is unreachable and connections time out. This site is otherwise fine and globally accessible via IPv6, tested on both Qwest and T-Mobile hosted systems. This is a regression from some time in early April this year. -- Tom
