No, the DNS was working. It was trying to connect to a specific ipv6 
address to sync, and failing (twice.)

That's what I initially thought too, but checked name resolution and it 
was returning proper addresses.

I even thought (before I started to remove systemd from my old laptop) I 
could save time by disabling ipv6 on the ISP router (my cell phone 
suffers the same delay), but then it wouldn't even connect to their network.
