What is DNS propagation?
When you change a DNS record, servers around the world keep the old answer until it expires. Propagation is the time it takes for all of them to show the new one.

DNS Propagation Checker FAQ
How long does it take?
Usually minutes to a few hours. It can take up to 48 hours if the old record had a long TTL.
Why do servers show different answers?
Some still have the old answer cached. They update when the cache time (TTL) runs out.
Can I speed it up?
Lower the TTL a day before you make a change. After the change, there is no way to force other servers to refresh.
