There's even a NANOG thread or two in there.

Hi, I'm new to the nanog list, hope this isn't out of scope for what is 
usually discussed here. 

Cogent is telling me that I can't route through cogent to get to google ipv6 
routes (particularly the well known dns addresses 2001:4860:4860::88xx) 
because google decided not to advertise those route to one of their mutual 

Anyone know anything about this ? .and why it happened and when it will be 
resolved ?
