Incomprehensible visits to the site from the USA, how to deal with?

Question

Fight against spam

Good time of the day!
For more than a week now, strange ip networks from the USA (with ipv4 address block not managed by the ripe ncc) have been constantly visiting the site!
Because of this, I constantly get from the Yandex webmaster - "The pages of the site https://site.ru on average take too long to respond to the robot"
Yes, and the hoster swears that "Critical load on the server"
Tell me how to deal with this, obviously these are not search engines ))
Maybe someone came across and knows what to do with it.

I would be grateful for any help.
Thank you.

All this will pass for you when the link ping that you yourself ordered somewhere ends ... Either ask him to remove (cancel) or make a GEOIP filter on the site.
