Cloudflare UAM Dstat — Live Under Attack Mode
Connecting…What is a Cloudflare UAM Dstat?
This Dstat target runs Cloudflare's Under Attack Mode (UAM): every new visitor is served an interstitial JavaScript challenge that the client must execute correctly before any request reaches the origin. Plain HTTP floods score zero here.
Cloudflare UAM Dstat FAQ
What is Cloudflare Under Attack Mode (UAM)?
Every new visitor gets a ~5 second JavaScript challenge page. Only clients that execute the challenge correctly receive a clearance cookie and reach the origin.
Why do normal HTTP floods show zero on a UAM Dstat?
Because raw HTTP requests never pass the challenge — they receive the interstitial page and are dropped. Only traffic from JS-capable clients (real browsers, headless browsers, or solver tools) gets counted as passed.
What does a high passed share on this page indicate?
It indicates the traffic source can solve the UAM challenge at scale — typically meaning headless-browser-based or clearance-cookie-reusing methods, which are far more resource-intensive than plain floods.
