We peer with Netflix directly on an exchange, and transit Level3, Cogent,
HE TW.
In me experience, when our direct peer is down for whatever reason, Netflix
prefers Hurricane Electric no matter what - if the route is there, it takes
it - then Cogent, then Level3, then TW.
I agree that the
We have used Ubersmith here ata Data102 for several years (since
august 2009? I think?) and have been very pleased with it. As a
datacenter operator, it provides a truckload of tools and (perhaps the
most important thing about it) integrates it all together pretty
seamlessly. For a simple example
Good morning,
We're in the market to move our IX peering off of our core (too much
BGP/CPU :-/ ) and onto a dedicated switch.
Anybody have a recommendation on a switch that can do the following
without costing a fortune? I have scoured Cisco, and bang for the buck
is ... ASR9k (way over powered
We use/d nfsen extensively for this this past November December and have
been very successful in planning our bandwidth purchases since then. We
like it so much that reliable, full-speed Netflow telemetry is now a
requirement on all edge/core routers.

Hey NANOG!
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.

Yep, we started seeing this right around 12:20pm MST. We saw it from a
customer's rapidly-flapping BGP peer. We told them to configure bgp
maxas-limit, but apparently CRS1s don't have that command.
Anybody have a handy route-map that will deny anything with a as-path
longer than say 15-20? ;-)
I agree with this whole heartedly. Phil Smith's presentations and
papers are fantastic. I'm certain that a sizable portion of the
Internet operates because of the material that he has, and continues
to, put together.

I'll second that. My Google-everything has been totally rocked all

That is a very interesting paper. Seriously, 7mpps with an

handful of them as hot spares and still save a bundle.
Highly recommended reading, even if (like me)

We're getting the run around from Network Solutions e-mail front-end

Basic problem is that we have a client mail gateway that is unable to

Anybody have any insight into what's happening to ATT? Internet Pulse is
