Every time I deploy anything new, I set up;
Public DNS; 1.1.1.1, 1.0.0.1, 8.8.8.8 (if tertiary configurable)
Public NTP: 0.uk.pool.ntp.org, 1.uk.pool.ntp.org, etc.
I do have DNS and NTP servers configured in my home, work, and lab networks, but as none are really for production I end up using public for simplicity.
