Notice the big difference in ping time between hops 3 and 4. I'm in San Francisco using the Fremont endpoint pinging Google in Mountain View, so these packets are never leaving the Bay Area. So why the big delay on HE's own tubes?

Form www.peeringdb.com about google
We peer IPV6 routes at AMS-IX Amsterdam, Equinix Ashburn & WIDE Toyko
4 hop is Ashburn so that's on the other side of US from Bay Area.
The difference is noticible - like 70 ms. But from Europe to US you would get >110ms.
Ah, ok. I assumed I was getting routed to the Googleplex but I guess they put their ipv6 server elsewhere.
