TTL Trade-off Between Performance and Update Speed

5/10 Medium

High TTL values (e.g., 24 hours) improve performance by reducing resolver queries but delay record updates by up to 24 hours. Low TTL values (e.g., 5 minutes) enable quick changes but increase authoritative nameserver load and may increase latency.

Query: “What are the most common pain points with DNS for developers in 2025?”4/9/2026

High TTL (e.g., 24 hours): This is better for performance because resolvers can answer from their cache more often. The downside is that any change you make could take up to 24 hours to be seen by all users. Low TTL (e.g., 5 minutes): This allows you to make changes quickly, which is great for website migrations. The downside is that it can increase the load on your authoritative nameservers.
