WordPress Host XML-RPC Ratelimit Test
The WordPress mobile app and Jetpack need to be in constant communication with a WordPress site's xmlrpc.php file.
There are times when all of those checks will pass in a single test, but fail for the user because there are repeated requests that are being rate limited.
This tool will send a cURL request to the target URL's xmlrpc.php file 50 times and return the http response codes.
