There is little you can do on the server against targeted DDoS. But you can  stop IPs with a lot of connections to your tor daemon using dynamic exit  police¹ or dyn. IP/nftable rules². For targeted help, you should specify the  type of relay you have and your OS.  https://gitlab.torproject.org/tpo/community/support/-/issues/40093  ¹https://github.com/artikel10/surgeprotector  ²https://forum.torproject.org/t/is-tor-network-resistant-to-tcp-syn-flood-dos-attacks-from-outside-of-tor/12690/4  --  ╰_╯ Ciao Marco!
