How significant are Cyber Week shopping days on the Internet? Is it a global phenomenon? Does E-commerce interest peak on Black Friday or Cyber Monday, and are attacks increasing during this time? We try to answer these questions and more.

If we plot the metrics associated with large DDoS attacks observed in the last 10 years, does it show a straight, steady increase in an exponential curve that keeps becoming steeper, or is it closer to a linear growth? Our analysis found the growth is not linear but rather is exponential, with the slope varying depending on the metric (rps, pps or bps).

The number of DDoS attacks spiked in the third quarter of 2024. Cloudflare mitigated nearly 6 million DDoS attacks, representing a 49% increase QoQ and 55% increase YoY.

In this post we will describe how we use anomaly detection to watch for novel DDoS attacks. We’ll provide an overview of how we build models which flag unusual traffic and keep our customers safe.

Over the past couple of weeks, Cloudflare's DDoS protection systems have automatically and successfully mitigated multiple hyper-volumetric L3/4 DDoS attacks exceeding 3 billion packets per second (Bpps). Our systems also automatically mitigated multiple attacks exceeding 3 terabits per second (Tbps), with the largest ones exceeding 3.65 Tbps. The scale of these attacks is unprecedented.

See how the first 2024 US presidential debate between Kamala Harris and Donald Trump influenced Internet traffic patterns compared to the Biden-Trump debate. We also review email trends and observed attack activity.
