Netflix transit preference?

I'M they would be more then willing to work with you on the open connect
appliance, specifically if you offered to pay for the hardware which I'M
sure would come in a lot cheaper then transport/transit over 12 months.

Hey Patrick,
Thanks for your prompt response. Yes, we are trying to determine where/how
we receive it ... not necessarily influence it, as there isn't so much we
can do there as Netflix' egress policy is theirs and theirs alone
(interestingly, nobody has communities to influence Netflix' AS2906
traffic). We cannot peer directly with Netflix as their openconnect
statement requires 2gbps minimum, and mentions elsewhere that the like 5+.
We aren't at 2gbps yet, and we are nowhere near one of their POPs -- it is
way cheaper to buy 2-3gbps of cheap transit than it is to buy 2-3gbps of
transport from Denver to LA.

As mentioned, my notes to peering at have gone unanswered for the
holidays (not unexpected), so I thought I'd ping the hive mind for some
info in the meantime.
