What is the typical TTL (Time To Live) value for DNS records managed by Cloudflare, and why is it important?

Cloudflare often uses dynamic and aggressive TTL values, typically defaulting to 300 seconds (5 minutes) for records managed through their proxy. For 'DNS Only' records, the TTL is inherited from your previous DNS provider or can be set by you. A lower TTL means that changes to your DNS records will propagate faster across the internet, which is beneficial for quick updates and failover scenarios.
