Cloudflare’s 2024 Radar Year in Review highlights Internet-wide trends across traffic (+17.2% YoY), adoption (HTTP/3 at 20.5%, IPv6 at 28.5% of dual-stack, 13% post‑quantum TLS), connectivity (225 major outages, strong speeds/latency in Spain, 41.3% mobile traffic), and security/email security (6.5% of traffic mitigated; U.S. and cloud platforms as top bot sources; Gambling/Games and Finance most attacked; Log4j still heavily targeted; 4.3% malicious email dominated by deceptive links and identity deception; certain TLDs overwhelmingly spam/malicious). It also notes Starlink’s rapid growth, shifting AI crawler activity, browser/search market shares, and improvements in routing security (RPKI), with country-level comparisons to inform security posture and IT strategy.
