[outages] AT&T & Google Issues

We are noticing a packet loss issue on our AT&T circuit to Google service. I have an open ticket with AT&T but they insist that it is a google issue. We are getting 50% packet loss to both www.google.com and 8.8.8.8. These are both taking the same route jumping from AT&T to Google. Trace route & pings are good up to 12.94.87.18. AT&T says that is google's router even though it is there IP. Anyone know how to let google know there is an issue with one of there AT&T pipes? -Louis
