10 hours age, I found my website unreachable. Then I checked that the server CPU become 100%. I didn’t make file changes for few weeks so I think it might not be a coding problem. I then check the requests on Cloudflare and found that the requests number is doubled and sometimes tripled. There traffic is even lower than usual. Traffic is below 100 in 30minutes(normally about 300 in 30 minutes).
I am new in website development. Any method to check if I am underattack? Please advise.

Thank you everyone for spending your time to read my stupid question.
