Here, I've also queried just ubuntu.com which resolves fine, for reference.

This set up is querying the DNS server given by DHCP, and is my ISP's router. Now, checking with `dig` directly against 192.168.1.1 (the router), dig complains that "Warning: Message parser reports malformed message packet.". And indeed, for the domains that do not resolve, this warning is always given by dig, when I query the router. It would appear that the router or its upstream is somehow breaking the DNS packets/responses and I'll have to figure that one out separately. The bug here is that systemd-resolved is failing on those while every other resolver seems to be working fine with those (supposedly malformed) replies. All other devices in the network, phones, windows, ubuntu 16.04, etc... are resolving with those just fine. Most notably, I can't resolve "buy.ubuntu.com". I've captured the packet/reply I get from my router, it's attached.
