> Did anyone really think that every time someone makes a DNS update it is broadcasted to every DNS resolver on the internet?
Absolutely. All of these, especially to an average person, imply the data takes a while to be pushed out "across the internet".
GoDaddy [1]: "but it can take up to 48 hours for everything to propagate across the Internet"
Namecheap [2]: "it is a period of time ISP (Internet service provider) nodes across the world take to update their caches with the new DNS information of your domain."
AWS [3]: "DNS propagation is the amount of time that it takes for DNS changes to be updated across the internet"

- meetups323 5y agoThose are both true statements. They also don't imply a push model.

- dreyfan 5y agoI don't really see the point of your comment, besides to express some sort of overly pedantic characterization of push vs pull event propagation techniques.
- whimsicalism 5y agoYou're the one making the distinction.
- dreyfan 5y agoAm I? I don’t have a horse in this race. I responded because I felt the “Did anyone really think” comment was arrogant and dismissive. I provided examples where a layperson could easily reach that conclusion.
- robertlagrant 5y agoThey do imply a push. A pull would mean that things mightn't spread across the internet in the event no-one requested them. Those statements do imply that things just get spread across the internet automatically.
- whimsicalism 5y agoCan news propagate?
- robertlagrant 5y agoIf someone claimed that in 48 hours everyone on the planet would've heard some news, that would imply a push, yes.
- whimsicalism 5y ago"By 48 hours, the news will have spread around the globe." (a more natural phrasing than propagate in the context of news, but I think pretty identical in implication) does not imply a push model, I just completely disagree with you.

- tshaddox 5y agoYes. It’s the effect that propagates.

- efdee 5y agoWhich, again, just translates to "but it can take up to 48 hours for other nameservers to have caught up".
