The text discusses how CloudFlare, an internet service provider, uses Domain Name Service (DNS) to enhance performance and security for its customers. One of the unsung advantages of using CloudFlare is that it eliminates the need to wait for TTL record expiration and DNS propagation when changes are made to a site's DNS records. This significantly speeds up development and deployment processes, making website management easier. Additionally, recent improvements have been made to CloudFlare's DNS management interface, and users can also manage DNS via API.
