why Yahoo! took a long time to update the domain dns setting?12 months ago - 1 answers
The time it takes for changes to your DNS to propagate is not something that Yahoo! has any control over. Due to the distributed nature of DNS directories on the Internet, it can take a maximum of 72 hours for updates to replicate across the globe. Generally speaking, the closer you are to the servers where the changes are made, the faster you will see the changes.
