What is DNS Propagation?
The time it takes for DNS changes to spread across all servers on the internet.
Why It Matters
DNS propagation means domain changes are not instant, and users in different locations may see old settings temporarily.
Real-World Example
After changing your domain's DNS records, some users may still be directed to the old server for up to 48 hours.
“Understanding terms like DNS Propagation matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
