You can register with every geolocation service known to man

a new one now. 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

Is there a good tool for comparing queries between

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 make sure we
are getting good CDNs and the like
