DNS propagation — how long does it take?
Why DNS changes are not instant, what TTL means, and how to know when the world sees your new records.
Caching everywhere
Resolvers at ISPs, offices, and public DNS services cache answers to speed up browsing. When you change a record, old values linger until the Time To Live (TTL) expires — not until you hit save in the panel.
Typical timelines
With a 300-second TTL, many users see updates within minutes; with 3600 or 86400, expect hours to a full day. Global propagation rarely exceeds 48 hours for common record types unless nameservers themselves changed.
Nameserver changes are slower
Pointing the domain to new nameservers (for example moving DNS to Cloudflare) is a bigger step than editing one A record. Allow extra time and avoid parallel edits at the registrar and new DNS host.
How to verify
Use lookup tools from multiple networks — office Wi‑Fi, mobile data, and an external DNS checker — rather than only your laptop. Clear local DNS cache only on your device; it does not fix the internet-wide view.
