unexpected RCODE (REFUSED) resolving

All-

I upgraded from 8.102 to UTM 9.0 latest soft release. When I reviewed the DNS log this morning, the log was very full with the following Rcode entries:

The noted entries are from this afternoon. However they have been going on since last night. Everything on the network was down over night except the ASG. I am not able to find a LAN based source causing this. Can someone please provide some direction? Outside of this UTM 9 works very nicely, a job well done! I seems very odd this would be coming from the ASG, but I believe it is possible. The 173. ***.***.*** addresses are google, and there are some 108.***.***.*** that belong to verizon. Thanks in advance for any help provided!

Regards,
Jim
