Re: Netflix transit preference?

More silliness was pointed out to me.  I was looking at Jeff Kell's from: address and looked up UTC.edu to get your 
location, forgetting you mentioned Colorado in your original post.

I'm going to sign off and enjoy the holidays since I clearly am not doing anyone any good here.

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.

Ah, I misunderstood.  Mea Culpa.  I thought you were saying since they only had 1.4 Gbps to you, you wouldn't peer 
with them.  Silly of me.

The 2 Gbps is only for PNI, but yeah, I can see how paying to get to LA or Denver may be expensive.  Although once 
you did, you could peer with a lot more than just Netflix.  On the other hand, how much is it to get to Atlanta?  
Looks relatively close (miles-wise, don't know fiber routes in Tennessee).

Anyway, while their egress decisions are theirs (as is true of everyone), they probably will be happy to discuss with 
you - once the holidays are over.

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

Cheers,

I work at a datacenter in southern Colorado that is the upstream bandwidth
provider for several regional ISPs. We have been investigating our
ever-growing bandwidth usage and have found that out of transits
(Level3,Cogent,HE) that Netflix always seems to come in via Hurricane
Electric. (We move ~1.4gbps to Netflix, and are thus not a candidate for
peering. And they have no POP close.)

Your statement about peering makes no sense.  You are trying to engineer where their traffic comes and yet you 
refuse to have a direct connection which would give you full control?  Weird.......


I tested this by advertising a /24 across all providers, then selectively
removed the advertisement to certain carriers to see where the bandwidth
goes. In order, it appears that if there is a HE route, Netflix uses it,
period. If there isn't, it prefers Level3, and Cogent comes last.

Completely unsurprising.


Since Netflix is a big hunk of our bandwidth (and obviously makes our
customers happy), we are included to buy some more HE. However, if Netflix
decides that they want to randomly switch to, say, Cogent, we may be under
a year-long bandwidth contract that isn't particularly valuable anymore.

With all of that, I am interested in finding out of any knowledge about
Netflix transit preferences, be it inside information, anecdotal, or
otherwise. I did email peering@ but haven't heard back, thus the public
question.

Why don't you ask Netflix?

And why not ask them for kit to put on-net?  <https://signup.netflix.com/openconnect>
