I don't see what they did wrong. You logged into their interface and told them that they were no longer the authoritative source for your domain by altering the NS records for your domain and you expected them to continue to host records for a domain for which they no longer think they are authoritative? Did your service contract with them include publishing DNS RRs for some period of time after altering your NS records to some other hosting arrangement? Once upon a time, a NS change with a registrar would actually take 72 hours. Now it's more like 5 minutes or less (even though they still say 72 hours). So once you change it, the effect is almost immediate and any DNS clients that have not yet cached your NS will almost immediately begin hitting the new server in the NS delegation. > 1 and 1 obviously has no idea how DNS works. Many do not... but I don't see this tale of woe as evidence that they do not. While it's true that they could potentially continue to serve up those records, thus keeping your domain alive for DNS resolvers that happen to have cached the NS records for your domain, I don't see it as likely unless they sell it as a feature that places them above their competition as far as DNS stability is concerned. Or they could offer to allow you to include both sets of NS records which would allow DNS resovlers to cache both, and then after 72 hours you could remove the old NS records. Does anyone know of a domain registrar that will continue to serve existing RRs after you have configured your NS delegations for a domain to go somewhere else other than their DNS servers? Or that allow you to serve both new and old NS records as a way to mitigate downtime during NS changes? I'm not suggesting that this means they don't exist, I'm genuinely curious to know if they do exist. Of course, these questions aren't really relevant if you host your own NS records and you can plan your NS delegation changes as carefully as you like and have all the control over the transition period that you like (and not run the risk of DNS downtime).
