OP here. > Every related incident seems to be due to either nameservers temporarily/incidentally chanced away from CF (and CF's service not re-checking it perhaps) or the registration billing failing (which doesn't look to be the case since registration expires 2021[0]). The changes a week ago involves adding and deleting TXT and A records only. Cloudflare manages the nameservers I use as my registrar and I never changed them from the default. I just confirmed all of that in the Cloudflare audit log. > Unless something else happened, deleting the zone from your account doesn't affect the registration. Re-adding the domain will instantly allow you to view the registration info and likely transfer away; this would only not work if the zone is banned for some reason. Thank you so much! Trying that now.

i think the parent poster meant changes done by or for a registrar like shown in whois. Zone changes wont show up there.

  Cloudflare is my register and manages my DNS. I would expect anything them to log any significant changes to either in their audit log.

    i think that it would be rather unusual to update timestamps in whois (which i guessed the parent poster was referring to) based on updates to in-zone data. A transfer would be an example of something that would change information in whois and thus update the timestamp noted there for the latest update. it is sometime possible to infer the date of the latest change of in-zone data because the serial of the zone is often constructed by using a date and a counter. But that is actually just convention and not reliable. Its also unlikely the parent poster was referring to this.

      Huh. I definitely didn't make any such changes within the last two weeks. Maybe the whois date got changed because of something opaque and internal to Cloudflare?

        yes that is most likely what happened. A change of the nameservers with authority for your zone for example or updates of DNSEC keys would trigger that too, i think. But most commonly it probably happens when the domain gets a renewed registration period or the contact details for some person changed. btw here are the dates referred in whois for your domain: Updated Date: 2020-02-24T20:32:34Z Creation Date: 2015-06-09T15:34:37Z Registry Expiry Date: 2021-06-09T15:34:37Z looks like a change has been done even more recently.

        I believe the latest change happened afterwards when on judge2020's advice I re-added the domain to cloudflare which I think triggered a NS change back to them.
