How long DNS propagation takes

Introduction

When you change a domain’s DNS, the result is not applied instantly across the whole internet. That process is called DNS propagation.

During that period it is normal for some people to see the new website while others still see the old one.

How long it can take

There is no exact time for every case, but these are common references:

• Some changes become visible within minutes.
• In many networks they appear within a few hours.
• Full propagation can take up to 72 hours.

The time depends on DNS caches, internet providers and the type of change you made.

How to check whether it already propagated

You can review the change in several ways:

• By checking NS, A, CNAME, MX or TXT records.
• By testing from another Wi-Fi network.
• By using mobile data.
• By opening the domain in private browsing.
• By checking from another device.

Can propagation be accelerated

Global propagation cannot be forced, but you can reduce local confusion:

1. Clear the browser cache.
2. Restart the browser.
3. Try incognito mode.
4. Clear the local DNS cache.
5. Test from another connection.

On Windows you can use:

ipconfig /flushdns

Conclusion

DNS propagation can take from minutes to 72 hours. While it is happening, it is normal to see different results depending on the network or device.

If the domain still does not work correctly after a reasonable time, it is often no longer just propagation and the configuration should be reviewed.
