ShadowServer thinks I'm in Glen Ellyn. The IP block has never been in or near
Glen Ellyn.
One could assume that the middle of a week day is a light NetFlix
time and that they would be pointing you to the nearest location. If they
thought he was in Albuquerque, that could make optimal routing a bit difficult.
It wouldn't just be the gross latency, but the number of peering points and
hops with potential congestion issues.

I also don’t know how important it is that a CDN be “near” you.
By definition, you’re probably talking a sustained download, either a
video stream or some kind of large file download. And most of the time you
will see 4 parallel TCP connections. I really don’t think latency matters once
you start the download. What does matter is server balancing. If your DNS
server has correct geoIP but Netflix chooses to send your customers to a server
in Dallas, maybe their Chicago servers are overloaded or undergoing
maintenance. Do you really want to second guess their decisions? About all
you can do is make sure your DNS server is in the right place according to the
geolocation database services, and let the content provider decide what IP
address to hand out to your customers and how to route that IP (they may use
geoIP info to decide the routing, not the DNS).
Now, if your DNS server appears to be in a whole wrong part of the
world, that may have dramatic effects, like totally different content being
available because Netflix thinks your customer is in Europe or Asia.

used the wrong term
Ignore the term
Take cache out of thyne mouth
now, being a windows dick, I dont have torch
I want to simply be able to verify that appropriate CDNs are being
utilized
namebench is still running, I dont know what its output is going to be
This cant be a new thing, I see threads occasionally about content
being problematic in that users are getting less than desirable CDNs, it always
seems to boil down to DNS,
I just want a tool that will tell me where the content is coming
from. (in a perfect world, it would display on a map with a quality indicator
to that CDN, I dont have any expectation that that component of the tool would
exist)

I was not aware you could cache Netflix streams with a generic
caching server. Not only due to DRM, but also Netflix app switches streams
dynamically to match video quality to connection speed. Plus first the
customer authenticates to Netflix server, chooses what content to watch, etc.

Say a new movie is on Netflix. Or latest season of cards.
Everyone is going to want to watch it. So 1000 simultaneous backbone streams
to Netflix vs 1000 simultaneous streams to the caching server in your NOC. I
choose the latter.

I don’t understand how the caching server is going to help with
CDNs. Actually, with so much Internet content now being either dynamic HTML or
streaming, I wouldn’t think caching would be worth it, unless you are talking
about something like a Netflix OpenConnect appliance. Maybe you can cache
software updates, I’m not sure about that.

Geographically close CDNs. I want to make sure we are getting
content from Illinoisish rather than california for netflix, since all that
matters is netflix

For performance, look at queryperf which I think is provided by
ISC/bind.
I'm not sure what you mean by "we are getting good CDNs and the
like," though.

Im not all that concerned about speed since we are so small
there wont be a huge amount of benefit I would think. Im primarily wanting to
