Could a tertiary name service save your uptime?

So, a tertiary nameservice for UK government?


  1. This might help the UK Government actually figure out how many idle/active domains it has.
  2. This might help the UK Government with a whole bunch of really clever asset discovery and surface scanning — feeding the National Cyber Security Centre’s (NCSC) WebCheck service or figuring out what vulnerable Citrix or VPN services are internet-facing
  3. This might help figure out who is the ‘technical contact’ for domains, subdomains and so on — on what could be a per-zonefile basis, which is the most granular you can reasonably go
  4. This will provide resilient nameservices to the corporate email domains literally used to run the country.
  5. This will provide a known-good zonefile repository — including fun stuff like trend analysis over time if the tertiary nameservice operator is feelin’ fancy.


  1. Offer things in return, even if you think the service being free should be sufficient to make people want to use it (its not)
  2. Automatic introduction through the existing (and any new) registrars
  3. Making it easy to self-register and get going
  4. Asking nicely
  5. Set guidance/standards/policy as needed, including linking to how this will help mitigate risks and help organisations meet existing guidance/standards/policy
