[External] Spectrum networks IPv6 access issue

Wed Apr 26 21:27:23 UTC 2023

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!

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.
