I had a similar issue, but it was mainly only over IPv6. According to 
someone I spoke to at Google, bumping up the MTU might help (and did 
help for me). I don't remember my previous MTU (I think it was 1280), 
but once I bumped it up to 1480 or so, my packets stopped getting routed 
to Europe (from NY) and worked properly. Maybe a similar issue could be 
with their IPv4 routers? Try increasing the MTU.
