High 5 minute load average alert

Hi i just got an High 5 minute load average alert email and when i checked the I.P it was google 151.41.233.35.bc.googleusercontent.com and all the sites it was looking at was wordpress any idea why this would happen ?

Hello,

Can you let me, know how CWAF rules or modsecurity relate to this issue?

Thank you.

Are they not meant to stop things like these attacks on wordpress
