DNS propagation explained

What this solves

You changed nameservers or DNS records but the change isn’t visible everywhere yet. This guide explains why and how long it can take.

What is propagation?

DNS is cached by ISPs and resolvers worldwide. When you change a record, old values can remain in caches until they expire. Propagation is the time it takes for the new value to be seen everywhere.

Typical timeframes

Often 15 minutes to a few hours. In some cases up to 24–48 hours. TTL (time-to-live) on the old records affects how quickly caches refresh.

How to check

Use online tools (e.g. “DNS propagation checker”) to see what different servers worldwide return for your domain. Your own browser may still show cached results; try another network or device.

Tip: Lower TTL before making a big change so propagation is faster when you switch.

When to contact support

If propagation hasn’t completed after 48 hours or you see wrong values, open a ticket and we’ll verify your DNS.
