Cogent and Google no longer peered via IPv6

[Phil Benchoff]

As of Thursday 28 April at about noon (EDT) most of our  IPv6 inbound traffic
shifted to our backup ISP.  A little digging shows that we are receiving no
routes from AS15169 (Google) via Cogent.  They are no longer peered via IPv6.
No HE and no Google.  That somewhat limits the usefulness of our IPv6
connectivity via Cogent.

Anybody else notice this?
