In app/code/core/Mage/Customer/Helper/Data.php
this is hardcoded
const VAT_VALIDATION_WSDL_URL = 'http://ec.europa.eu/taxation_customs/vies/services/checkVatService?wsdl';
whilst new url is (I think)
const VAT_VALIDATION_WSDL_URL = 'http://ec.europa.eu/taxation_customs/vies/checkVatTestService.wsdl';
Explained here
