I am getting similar messages through my e-mail specified for debug errors in the Admin config for UPS XML. This seems to happen with every order I receive, although the orders appear to complete successfully each time. I haven't had any complaints, either, although no one has actually selected UPS as a shipping option (I also have USPS Rate and FedEx). When I use my test accounts and go through all the way to the payment page, I get no error messages whatsoever - even when I select UPS.
Does anyone have any ideas? Here's what I keep getting with each order - sometimes in multiples:
UPSXML Rates Error: 111210: The requested service is unavailable between the selected locations. experienced by customer with id on 2014-09-25 23:54:22
UPSXML TimeInTransit Error: 270032: Invalid Destination Postal Code and City experienced by customer with id on 2014-09-25 23:54:20
