What Is DNS Propagation?
After updating DNS records, it takes time for changes to reach all DNS servers worldwide. This process is called DNS propagation.
How Long It Takes:
✅ Typically 1–24 hours
⚠️ In rare cases up to 48 hours
Why It Happens:
DNS servers cache information to improve performance. When you update a record, cached values must expire before the new values appear everywhere.
How to Check Propagation:
Use tools like:
-
WhatsMyDNS.net
-
DNSChecker.org
Quick Tips:
-
Lower TTL (Time to Live) before big DNS updates.
-
Wait at least an hour before troubleshooting.
