Alto uso CPU vindo IP Google

Estou com um site com alto uso de CPU e não é por causa de muitos acessos, nos logs do servidor aparece como se fosse um ataque, mas vem do IP da google.

Já tentei fazer de tudo, até migrar de servidor eu tentei, mas nada resolve, mesmo que aumente a potência do server, vai consumir 100% de toda forma, isso só para se desativar o DNS por exemplo.

Tenta inicialmente algo no Wordpress como o plugin Wp Cerber.
Ele é bem eficiente para limitar bots e isso já pode resolver.
