Cloudflare is a service that “powers Internet requests for millions of websites and serves 78 million HTTP requests per second on average,” according to its site. In short, when Cloudflare has problems, the internet has problems. Users on X are already reporting issues, and Down Detector — the site that’s normally a go-to for checking what’s broken and what’s not — appears to be having issues itself. (Disclosure: Ziff Davis owns both Mashable and Down Detector.)
