DNS Propagation: Why Changes Take Time & How to Check
How DNS propagation works, why changes can take 24-48 hours, how to check propagation status, and how to speed it up.
Why DNS Takes Time
DNS records are cached at multiple levels: your browser (minutes), your OS (minutes), your ISP resolver (TTL value, often 3600s/1hr), and recursive resolvers worldwide. When you change a record, all these caches must expire.
Speed It Up
- Lower TTL to 300 (5 min) before making changes
- Wait for the old TTL to expire
- Make the change
- Raise TTL back after propagation
