Cogent and Google no longer peered via IPv6

[Frank Bulk]

We get to ipv6.google.com via Sprint today, even though we are IPv6-peered
with Cogent and Qwest and have (had?) an HE tunnel as well.  I used RIPE's
bgplay and there was no indication of routing changes for Google's IPv6
prefix.

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?
