Synchronous flow vs. immediate effect in DNS #166
Description
I'm suspicious of the synchronous flow. Is it common for DNS providers to be able to make updates in real time? I would expect - especially in cases where DNSsec is supported - that it might be better to be able to accept a request (so the sender is guaranteed it will happen eventually, possibly with an estimate or commitment as to how long it will take) rather than delaying a response until the update is completed, especially given that if there is a crash while waiting the requestor doesn't know whether he has to resubmit it.
[PK] The synchronous flow does not mean the changes are deployed and
propagated. "the sender is guaranteed it will happen eventually" is what
actually shall happen. I will take into the text if it may be put more
explicit.
