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:

Trying from another network and I was able to get through:

Maybe something in Hurricane Electric’s network potentially not getting these
packets where they need to go?
