CLOUDFLARE IPs Caused Massive Server Load. Why?

Hey guys,

Can anyone advice why IP (, < just a few), which shows as owned by CF was causing a massive server load? It’s making this request non-stop > “POST /wp-admin/admin-ajax.php HTTP/1.0”

Soon as I blocked the IPs through CloudFlare Firewall IP access rule, the load goes back to normal.

Appreciate any feedback.

Thank you!

It sounds like your domain is on Cloudflare, but your server is not restoring Visitor IP address. So it looks like Cloudflare is causing the load, but the requests are really coming from outside, just like all other traffic.
