DNS propagation, explained
What is DNS propagation?
When you change a DNS record or your nameservers, DNS servers around the world keep serving the old answer until their cached copy expires. Propagation is the time it takes for all of them to pick up the new value.
How long does it take?
Record changes usually show up within minutes to a few hours, depending on the record's TTL. Nameserver changes can take up to 24–48 hours to be visible everywhere.
Why do servers show different results?
Each DNS provider caches records separately. Until the old TTL runs out, some servers still return the previous value — that's normal during propagation. Click "Recheck" after a while to see the progress.
How can I make changes propagate faster?
Lower the TTL of the record (for example to 300 seconds) a day before you make the change. After the change is live everywhere you can raise it again.
