I am having a issue using Google's SDC (Secure Data Connector) with my Google App Engine application (my app is unable to get data from within my network but using a Google Docs spreadsheet I can get the data).
So I found this troubleshooting info: http://code.google.com/securedataconnector/docs/debug.html. and as suggested I added the debug header to url fetch and received the debug information back but I am not sure what it means:
sdc_routing : Internet sdc_internet_routing : USER_NOT_HOSTED
Thanks, Jamie
