Quad9, a free internet switchboard that amplifies security, has grown to 27 million users after launching with 1 million just five months ago.
Why it matters: Quad9 is a global, secure domain name system (DNS) — the thing that turns text-based internet addresses (e.g. axios.com) into machine-readable internet addresses. It is designed to protect privacy and halt other online threats. The growth of Quad9 and the introduction of competitors like CloudFlare's 18.104.22.168 demonstrate a global interest in privacy and security.
