Hi George,

thank you for reaching out. Sorry that I disturbed you. To mitigate this
issue AS8560 shut a connection to a carrier at Chicago. We will discuss
this issue with them.

Sorry for wasting your time and energy.

Have a nice weekend

Cheers Thomas

Hi Thomas,

We don't have any deny listing on e.in-addr-servers.arpa, and can see
requests from the 74.208.0.0/16 range. Can you please send further
details so we can help troubleshoot with you to [email protected]?

Regards,
George Salisbury
