Public bug reported: This is something new in Ubuntu 17.04. Whenever I boot up or upon returning from sleep, I don't have DNS resolution available. What I have to do is go and shutdown systemd-resolved (sudo service systemd-resolved stop) and edit /etc/resolv.conf to point to 192.168.1.1 (my router) instead of 127.0.0.53. Then everything works peachy. Otherwise any DNS resolution attempt will result in SERVFAIL.
Since this is a major issue out of the box and I don't see any other bug report on this yet, I wanted to report it. This happens both on my laptop and my desktop PC, so it's not something strange on a single machine, but since no one else is complaining about it yet, it may be related to my network configuration. My router forwards DNS requests to an ODROID C2 on the same subnet, which then does the DNS resolution via dnsmasq. Dnsqmasq is set up to forward the requests to multiple DNS servers and respond with whichever one was fastest.
