source: https://dns.google/resolve (DoH, DNSSEC-validating + CD=1 bypass)
notes: >-
  thistle.tech is the company's canonical domain but currently fails DNSSEC
  validation: the .tech parent zone publishes a DS record (keytag 1792, alg 8,
  digest type 2) for thistle.tech, yet the zone itself publishes NO matching
  DNSKEY, so every validating resolver returns SERVFAIL and the name does not
  resolve (curl/WebFetch see ENOTFOUND). With DNSSEC checking disabled (CD=1)
  the apex has no A/AAAA record (NODATA) and www / api / docs / developer / app /
  blog / portal subdomains are NXDOMAIN, so no web host is currently served. No
  MX and no TXT (no SPF) are published at the apex. Nameservers are DreamHost.
  Absence of records here is recorded, not inferred.
