Stop clean traffic to webserver

Hello, we are facing a lot of webserver performance issues and need to debug the live server. The high load of traffic prevents an efficient debugging. Is it possible by cloudflare to stop or even better just let 30 % of the traffic reach the webserver?


There is rate limiting, but I am not sure that will do exactly what you imagine, though it is not entirely clear based on what you want to block requests. I would suggest you familiarise yourself with as all features are documented there.

If you really want some custom 30% block, you’d probably have to go down the route of a custom Worker implementation where you implement the logic yourself in JavaScript, though be aware this will be paid unless 100,000 requests a day are enough for you.
