I believe this should be filed upstream instead.

  systemd-resolved negative caching for extended period of time

  If a DNS lookup returns SERVFAIL, systemd-resolved seems to cache the
  result for very long (infinity?). I have to restart systemd-resolved
  to have the negative caching purged.

  After SERVFAIL DNS server issue has been resolved, chromium/firefox
  still returns DNS error despite host can correctly resolve the name.
