Sub-optimal routing to Google via IPv6
I have noticed that since we deployed IPv6 a number of years ago, that our IPv6 routes to Google's V6-enabled sites (e.g. www.google.com and www.youtube.com) traverse the CONUS from Oakland (where our primary Level 3 ISP connection is) to Washington D.C., New York, and then onto Google's network in New York, where the packets presumably pass across Google's internal networks.

I haven't raised this issue with Level(3) yet, as I was wondering if this is really a Level(3) routing issue or a Google IPv6 routing issue? Thank for any insights.
