It seems CloudFlare was not working to protect the web from a DDoS attack.
I have tried to attack my server in several cases:
- Case 1: Using https://ddostest.me/, In this case, all 3 modes medium, high or even “I’m Under Attack” did not block or JS Challenge. All requests go through CloudFlare and go directly to my original server. So the server is down.
- Case 2: I created a .NET application to send requests to my server (1000 requests/second). In this case, only “I’m Under Attack” mode can protect my server, the rest cannot.
So can someone tell me more about CloudFlare’s anti-DDOS mechanism?
Can we prevent layer 7 DDoS attacks with Cloudflare?
