If you register a domain with Cloudflare or Route 53, and that service goes down, do your records stay active in the DNS servers? What if the DNS servers go down, I know a lot of people use 8.8.8.8, so if Google’s server goes down, then DNS fails?

What are the potential point of failures for having your own domain?

    If the DNS server for your Domain goes down the records should still be saved in all the other DNS servers around the world. They will stay the same as they were before you domain’s DNS server wen’t down. While your DNS server is down you won’t be able to change where the Domain points. While your registration server is down you will not be able to transfer or sell your domain.

      You should actually be able to transfer and sell - that’s handled at the tld.

      Also, there’s a lifetime to that cache, so if it’s down long enough it’ll become unreachable.

        I’ve never really understood the whole TTL thing. Will the domain essentially point to nothing if the TTL runs out while the DNS server is down or will it default to older record?
