Symptoms
Task named 'Unprovisoning siteWithHosting for APS Application Web Business Builder' NOT triggered by customer's removal action from WBB on UX1 or CCPv1.
This cause the customer's site to be removed from WBB and the corresponding hosted domain of the site detached from its Webhosting (apache or IIS).
Cause
The affected site corresponding domain DNS hosting was converted from Internal DNS hosting to external one using OSS public OpenAPI method pem.removeDNSHosting.
This method can be invoked through XML-RPC call from a remote machine (host) which has access to invoke said OpenAPI method on the CB Management Server remotely.
Or, it also can be invoked on the CB Management Server locally.
This is only true for cases whereby from the core log there is evidence that this has occurred few minutes before the WBB un-provisioning task was triggered.
Example of XML-RPC call made from remote host:

Resolution
Host which is allowed to invoke request through the public OpenAPI method to your CB Management Server means it is known to your infrastructure.
Regardless of the fact that such request was invoked locally or remotely. The purpose of invoking the request can only be known by inquiring the implementer of such request.
