However the effect being your site is down. It was DDoSed. DDoS=Distributed Denial of Service. I used a botnet==Distributed. And because it gave a frontend error, it was denying legitimate clients service. So you can wrap it up however you will. It went down lol.
TBH the host are skids anyway. Any old noob can set ngnix up with rate filtering to block such basic layer 7 attacks such as flooding HTTP GET requests lol
