Address: 72.5.65.111
Aliases: cdp1.public-trust.com

Thanks

I found the stray entry in an External Dynamic List (EDL) feed and was able to exclude entry until list provider was able to correct.

Is it possible that all that host traffic is being sinkholed due to quarantine actions? 

 

I checked, indeed that site is categorized as low-risk & computer/internet info, so unless you are explicitly sinkhole-ing low-risk sites, this should not be the case. 

 

Low sev TAC threat case?
