Hello!
Since 11:06am PST on Dec 4, I've had trouble resolving
gtfs.translink.ca from Google Public DNS from a Linux VPS located in Seattle (
tds.xyz). I'm currently experiencing the same failure from my Macbook in Orlando. The problem appears intermittently; hitting the resolver several times sometimes produces an okay result before reverting to failure. Other resolvers (Cloudflare, Level3) do not return failures.
From my browser, reload-spamming
dns.google.com/resolve occasionally returns a failure like:
{"Status": 2,"TC": false,"RD": true,"RA": true,"AD": false,"CD": false,"Question":[ {"name": "
gtfs.translink.ca.","type": 1}],"Comment": "Resolution failure. Please check
https://intodns.com/gtfs.translink.ca"}
But usually returns the "correct" answer:
{"Status": 0,"TC": false,"RD": true,"RA": true,"AD": false,"CD": false,"Question":[ {"name": "
gtfs.translink.ca.","type": 1}],"Answer":[ {"name": "
gtfs.translink.ca.","type": 5,"TTL": 21599,"data": "
gtfs.cloudapp.net."},{"name": "
gtfs.cloudapp.net.","type": 1,"TTL": 59,"data": "168.61.12.60"}],"Comment": "Response from 13.107.160.201."}
A failure looks like:
$ dig @
8.8.8.8 gtfs.translink.ca; <<>> DiG 9.10.6 <<>> @
8.8.8.8 gtfs.translink.ca; (1 server found)
;; global options: +cmd
;; Got answer:

And a success from Cloudflare's resolver looks like:
$ dig @
1.1.1.1 gtfs.translink.ca; <<>> DiG 9.10.6 <<>> @
1.1.1.1 gtfs.translink.ca; (1 server found)
