Hello guys, my site suddenly experienced high CPU usage. Do you know why it's happening? Can anyone help? Am using Hetzner powerful server. Most traffic it feels from bots.
cache anonymous requests, challenge or block “bad” bots with WAF, use persistent object caching if you aren’t, etc
Bots can cause the highest CPU activity among other things. In your events in Cloudflare you can see what bots are visiting and set a rule to block the repeat offenders. Can also turn on bot fight mode to see how cpu traffic changes.

Could also be bad scripts. This tool was mentioned yesterday https://www.blackfire.io/
