Re: Spectrum residential IPv6 issues - contact off-list ?

["J. Hellenthal via NANOG" <nanog () nanog org>]

Port 80, 443, 873 are open on v4
Port 80 is open on v6
ICMP is not available on v6

I am assuming the problem you are noticing is due to protocol that you are trying to reach?. The ping you are using 
reported on outages does not really say much to the problem you are having. I would reach out to https://colohouse.com/ 
to inquire further as a change in their firewall or routing may be impacting the problem you are seeing with v6 only.
