[public-dns-discuss] Google DNS Nameservers returning no answer for tillerhq.com lookups



Hello,

Hover.com, who hosts our DNS servers had an outage tonight, and now I am unable to get dig to show an an address for sites in our domain (tillerhq.com).

Here's the Twitter exchange for context:

https://twitter.com/TimJohnsWA/status/968342848121769988

Per https://developers.google.com/speed/public-dns/docs/troubleshooting:

Step1: 
  intoDNS shows one error, no 'A' record for www (by design -- it's a CNAME record referencing our site on SquareSpace)
  DNSViz showed no problems


Note: Results in steps 2-5 are for sheets.tillerhq.com, which is running in GCP, but we're getting the same results for other sites (i.e. www.tillerhq.com) hosted elsewhere (SquareSpace).


Step 2:
bash-3.2$ /usr/sbin/traceroute -n -w 2 -q 2 -m 30 8.8.8.8
traceroute to
