Google Peering/Edge Network Contact?

Does anyone have a contact for Google Peering / PNI? We have a caching appliance whose BGP session has been flapping nonstop for the past month or so. We've had a ticket open with Google since it started, but they haven't really made any headway, or provided much of a response.
