Cloudflare DDoS Threat Report H1 2026: 1 Tbps attacks soar as DNS floods and geopolitical tensions drive a new wave

Cloudflare's H1 2026 DDoS threat report documents a sharp increase in mega-scale attacks, with 935 incidents exceeding 1 Tbps and a 519% quarter-over-quarter surge in Q2. Attack patterns shifted from traditional botnet floods toward DNS-based reflection and amplification techniques, which represented 34.3% of recorded attacks.

Why it matters: Organizations relying on internet-facing services need to assess their DDoS mitigation capabilities against larger attack volumes and evolving reflection-based attack vectors that exploit DNS and similar protocols.
