Hardcoding 8.8.8.8 or any other DNS is a hacky workaround systemd networkd not properly setting up resolv.conf based on DHCP info. An easy solution - move to network manager. It actually gets this right. It will also handle multple network interfaces (if you plug in some USB ones) as well as Wifi (via USB) if you attach it etc. so use a better solution. Network Manager.
