Overview
DNS changes can take time to spread across the internet. This delay is often called propagation. During that period, some visitors may see the new destination while others still see the old one.
What Affects DNS Timing
- How recent the previous DNS records were cached
- The TTL values on those records
- The device or network used to check the site
- Whether the change involves nameservers or only individual records
What You May Notice
- Your website works on one device but not another
- Email starts working before the website changes finish
- A temporary mix of old and new behavior during the transition
What Not to Do
Avoid making repeated DNS changes too quickly unless you are sure they are needed. Constant changes can make troubleshooting harder and extend confusion.
If you are moving a live business website, plan the switch carefully and review our migration and DNS guides before changing anything.
