I’m in the northeast and I can confirm on a Spectrum Enterprise connection I have issues tracerouting to 2604:1380:4641:c500::1. Gets to e0-33.core1.nyc7.he.net and then packets just disappear: Host Loss% Snt Last Avg Best Wrst StDev 1. _gateway 0.0% 108 1.0 1.7 0.8 26.3 3.3 2. 2602:XXX:XXXX:X::X 0.0% 108 4.4 6.6 4.2 27.9 4.0 3. 2602:XXX:XXXX:X::XXX 0.0% 108 3.1 3.0 3.0 3.5 0.0 4. 2604:XXXX:X:X::X:XXXX 0.0% 108 5.2 4.8 3.3 37.1 5.0 5. lag-15.srspny0101h.netops.charter.com 0.0% 108 3.9 20.8 3.6 371.6 45.4 6. lag-32.albynyyf02r.netops.charter.com 44.4% 108 4.9 4.9 4.8 5.5 0.1 7. lag-26.rcr01albynyyf.netops.charter.com 80.4% 108 5.1 5.3 5.0 7.7 0.6 8. lag-416.nycmny837aw-bcr00.netops.charter.com 57.9% 108 37.4 14.5 12.7 54.4 7.1 9. lag-1.pr2.nyc20.netops.charter.com 0.0% 108 49.8 17.1 12.3 65.7 11.0 10. e0-33.core1.nyc7.he.net 0.0% 108 12.9 13.2 12.8 19.8 0.7 11.

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.
