DNS doesn't “propagate”
> When people say “we’re waiting for DNS to propagate”, what they actually mean is “we’re waiting for cached records to expire”.<p>And when people say "the new data needs to propagate" they usually mean "all the old versions of the data need to be replaced with the updated version". Which is exactly the what "waiting for cached records to expire" means. I don't really see the point of this article, besides to express some sort of overly pedantic characterization of push vs pull event propagation techniques. Did anyone really think that every time someone makes a DNS update it is broadcasted to every DNS resolver on the internet?<p>Edit in response to general feedback: The article should be titled "DNS doesn't push". The DNS consistency process satisfies any reasonable definition of "propagation" so claiming "DNS doesn't propagate" is confusing at best and misleading clickbait at worst.
