WordPress/4.8 HTTP client accessing itself

I found a pretty bizarre problem. The server itself is showing up frequently in the Apache logs, with the client “WordPress/4.8; https://my-site.com”

It claims to be referred from a particular page and retrieving that page over and over. I’m using ithemes and have XML-RPC disabled and the REST API restricted. Nonetheless the logs were filling with this entry over and over.

The page in question is one page of our blog from 2007, I took out and looked at the post content and found nothing special.

What would make the wordpress HTTP client access a particular page like this?

Thanks!
