So far my Live Rates from USPS are functioning normally. Even International shipping methods.

The real impact for me has been the rate increase.

Has anyone noted any changes? I am trying to configure my USPS, but no options show for US Domestic or International Shipments originating in the US. USPS says that my API is live and active.
