DNS TTL & Caching Health Checker

Analyze your domain's DNS TTL settings under two key lenses: Everyday Page Load Latency vs. Server Migration Readiness.

Optimal DNS Caching Balance
Your DNS TTL settings strike a healthy balance between fast initial DNS connection speeds and reasonable infrastructure agility.
2. Server Migration Agility
Migration Ready
Ready for Fast Server Migration
Your primary web resolution records (A/CNAME) have low TTLs. If you switch web hosts or server IPs today, DNS updates will propagate globally within minutes with minimal downtime.

Actionable Recommendations & Best Practices
[Best Practice] Post-Migration TTL Restoration

Once your server migration is complete and verified stable for 24 hours, remember to raise your TTL values back to 3,600s or 86,400s to regain optimal DNS caching performance.

Understanding DNS TTL: Performance vs. Agility

DNS Time-to-Live (TTL) is a numerical setting (measured in seconds) attached to every DNS record. It dictates how long recursive DNS resolvers, ISPs, and web browsers are permitted to cache your server's IP address before requesting a fresh update.

Why Low TTL Hurts Everyday Speed

When you set a low TTL (e.g. 300s / 5 minutes) on a domain that is not migrating, every returning visitor's browser or local ISP must continuously send fresh DNS queries to resolve your server IP. This adds an extra 20ms to 150ms round-trip latency to page load times. For everyday stability, TTLs should be set to 3,600s (1 hour) or 86,400s (24 hours).

How to Manage TTL for Zero-Downtime Migration

If you are planning to switch web hosts or move to a new server IP, follow this two-step process:
1. 24 hours BEFORE migration: Reduce your A and CNAME TTL values to 300s (5 minutes).
2. 24 hours AFTER migration: Once the new IP is verified stable, raise your TTL back to 3,600s or 86,400s to regain maximum DNS caching speed.
