This post introduces time.cloudflare.com, a free time service supporting NTP and the emerging Network Time Security (NTS) protocol. It highlights the critical role of accurate and secure time synchronization for internet security, detailing vulnerabilities in the original NTP protocol and the need for cryptographic authentication. This expands the scope of the DNS Infrastructure thread to include the security of other fundamental internet protocols that rely on accurate time for their security guarantees.
