Experiences with IPv6 peering?

To amplify Nick's point, if you use Cogent's IPv6 connectivity you need to
use at least one other IPv6 provider, even if it's a tunnel with Hurricane
Electric that appropriately preprended.  And if you want redundancy when
Cogent is in the mix, you should have a minimum of three IPv6 providers.

For table sizes, see here: 

I'd recommend making your Cogent account manager aware of this table.  It
was actually created (by someone else) after I spoke with our (prospective)
Cogent account rep's supervisor who claimed that Cogent was "in line with
their competitors" and "growing like everyone elese". Na, na, na, naah.
They're at the bottom.

Welcome to being single homed behind Cogent's ipv6 network.  Your options

1. live with it
2. complain to your account manager at Cogent
3. get ipv6 transit from another provider

As far as I know, a lot of people have tried option #2 and have eventually 
resorted to option #3, either to complement or as a replacement for their 
Cogent connection.

HE's position on this is documented here:
