[External] Spectrum networks IPv6 access issue

Wed Apr 26 17:46:14 UTC 2023

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.
