That looks about right.
Always glad to be able to help remove boredom! Other than my comp chem
calculations, I find boredom to very boring.
At least one of us doing real science. I'm ashamed to mention what I do
for the living ???.
And now to the fun part. Please provide these:
tcpdump -ni any -s0 -w /tmp/fastly.pcap tcp port 80 or icmp6 or \
udp port 53
ip a l
ip ro l table all
traceroute -n 2a04:4e42:b::204
It should be noted that:
1) tcpdump should be run while you're invoking apt-get, with IPv6 stack
operational (i.e. no disable_ipv6 trick).
2) To terminate tcpdump use Ctrl+C. All its output will to to a file.
3) tcpdump will capture all tcp:80 (i.e. - HTTP), that's intentional.
This may, or may not be a privacy issue.
4) tcpdump requires CAP_NET_RAW and CAP_NET_ADMIN to function properly.
Meaning - you run it as root. Other commands should not require root.
5) If tcpdump is not installed there, use disable_ipv6 trick temporarily
to apt-get it.

After installing tcpdump I got:
