Two of the three AAAA records for releases.geo.mozilla.com point to hosts that are unreachable on tcp/80:

% host -t AAAA releases.mozilla.org

% nc -6vv 2610:148:fd80:3d6f:209:3dff:fe12:7bf9 80
nc: connect to 2610:148:fd80:3d6f:209:3dff:fe12:7bf9 port 80 (tcp) failed: Host is down

% nc -6vv 2001:4f8:0:2::1f 80                     
nc: connect to 2001:4f8:0:2::1f port 80 (tcp) failed: Operation timed out

% nc -6vv 2001:6b0:e:2018::158 80
Connection to 2001:6b0:e:2018::158 80 port [tcp/http] succeeded!

This is a serious problem for users of Mozilla products at Virginia Tech (vt.edu) since the entire main campus network, including residence halls, is dual-stack.

Reproducible: Always
