    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
