Thanks Travis for your work on this.
Here is a little update:
On Wednesday April 22nd at 21:14 (GMT+2) we got an email informing us that the processing was put on hold since the Autotask API was unavailable.
I’m not sure if this was the first kind or the second kind of failure but we did not get any messages about no XML document.
Here are some examples in which the processing was successfully paused and resumed:
