Web Content Filtering is blocking ajax.googleapis.com which hosts jQuery etc

We have a pretty standard Web Content Filter Policy set up, but today it's started blocking the  ajax.googleapis.com domain which hosts jQuery and a bunch of other JavaScript libraries.

In the Defender logs we see the block also

 

Seems like a pretty obvious false positive.

        Marked as illegal software.. interesting 🙂 I'm having illegal software blocked as well, somehow its not triggering on ajax.googleapis.com .. (luckily)
