Whenever I make changes to DNS I have noticed that it takes hours to propagate when viewing from my wired connection but with minutes I can see the changes reflected when browsing on my mobile, 3g T-mobile network.
I really would like to understand why this happens.
With regards to the question being closed: The question is fine. Closing it for not being "relevant to professional system administration" is both incredibly annoying and incorrect.
Is this due to the terminology I used in the question or the content?
