In 2023, DDoS disruptions were already happening at a speed that feels almost unreal. Cloudflare mitigated 20 million attacks in Q4 2023, yet 98% of them were handled within 10 seconds, and a huge share were over in under 5 minutes. Still, the pressure behind the scenes adds up fast, from UDP floods driving most volumetric blasts to DNS amplification climbing at Akamai as the overall global volume reached 15.4 million.
