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.
