1 Tbps DDoS Attacks Become the New Normal as Cloudflare Reports Record H1 Activity
Brief
Cloudflare has reported a sharp rise in large-scale distributed denial-of-service attacks during the first half of 2026, blocking 935 network-layer attacks exceeding 1 terabit per second.
The company said hyper-volumetric attacks grew 519% between the first and second quarters, showing that attackers are increasingly capable of delivering extreme traffic floods at a rapid pace.
The findings appear in Cloudflare’s 25th DDoS Threat Report, which combines data from January through June 2026. Unlike previous reports that covered each quarter separately, this edition provides a half-year view of attacks observed and mitigated across the Cloudflare network.
During the period, Cloudflare mitigated 23. 2 million network-layer DDoS attacks and 29. 64 trillion HTTP DDoS requests. This amounts to roughly 5,343 network-layer attacks per hour, or about 128,000 per day.
