ddos

When I receive DDOS attacks, my processor usage goes to 100%, meaning Cloudflare is not mitigating. What can I do?

are the requests going through cloudflare? do you have dynamic parts of your website that require processing on your device?

If you are under a DDoS attack then you can take a look at these threads for first steps and help with mitigation: - https://community.cloudflare.com/t/mitigating-an-http-ddos-attack-manually-with-cloudflare/302366 (Community link) - https://developers.cloudflare.com/ddos-protection/get-started/ (documentation link)

Yes, requests go through cloudflare. I didn't understand the other question. Machine processor usage without attack: 15%, then with attack 75%, mysql using around 80% according to what htop says, and then when I disabled mysql the machine's cpu usage with the attack was 25% (+ 10%) then I activated mariadb again and it was at 70%. any suggestions for this? How do I disable any request to my website if Cloudflare detects ddos? Is it possible, if Cloudflare detects ddos from sources in a certain country, to block all people from that country from connecting to the site? If, for example, they send DDOS with a proxy from Portugal, blocking all people from entering the website if they are in Portugal until stopping requests from Portugal, is this all on the Cloudflare panel?
