In 2024 Cloudflare mitigated a staggering 21.3 million DDoS attacks—a 358% year-over-year jump—and in Q1 2025 alone it already repelled 20.5 million assaults, including 6.6 million aimed directly at its own infrastructure during an 18-day multi-vector campaign. The surge was driven by a 509% increase in network-layer attacks, while hyper-volumetric floods exploded: over 700 events surpassed 1 Tbps or 1 billion packets per second, averaging eight daily in Q1. Emerging threats like CLDAP reflection attacks rose 3,488% quarter-over-quarter and ESP amplification attacks grew 2,301%. Even specialized gaming servers faced hyper-volumetric onslaughts up to 1.5 billion packets per second. Most alarmingly, Cloudflare disclosed it withstood a record-breaking 5.8 Tbps DDoS blast lasting 45 seconds, eclipsing its previous 5.6 Tbps record. Although fully mitigated, these figures underscore unprecedented scale and sophistication that threaten service availability and corporate stability across industries.
