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.


Hey J,

I don’t think it’s that.  The mirror.steadfast.net <http://mirror.steadfast.net/> just happened to be something that 
also failed (I was installing Debian and the installer hung trying to use them as a mirror).

I’m on my backup internet now (not Spectrum) - and the ping works fine:

vom@onosendai 💀 ~ % ping6 -c 3 mirror.steadfast.net
PING6(56=40+8+8 bytes) MY_IP --> 2607:f128:1:3::2
16 bytes from 2607:f128:1:3::2, icmp_seq=0 hlim=56 time=16.965 ms

16 bytes from 2607:f128:1:3::2, icmp_seq=2 hlim=56 time=15.490 ms

--- mirror.steadfast.net ping6 statistics ---
3 packets transmitted, 3 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 15.490/16.575/17.270/0.777 ms

Hopefully someone from Spectrum can hit me up off list.  No offense to the front line folks but I doubt I will get very 
far with them on an issue like this...
