Personally, I don't think the content networks and CDN's should focus on
developing yet-another-speed-test-server, because then they are just
pushing the problem back to the ISP. I believe they should better spend
their time:

   - Delivering as-near-to 100% of all of their services to all regions,
   cities, data centres as they possibly can.


   - Providing tools for network operators as well as their consumers
   that are biased toward the expected quality of experience, rather than how
   fast their bandwidth is. A 5Gbps link full of packet loss does not a
   service make - but what does that translate into for the type of service
   the content network or CDN is delivering?

Mark.

That's why I vastly prefer stats from the actual CDNs and content providers
that aren't generated by speed tests.  They're generated by measuring the
actual performance of the service they deliver.  Now, that won't prevent
burden shifting, but it does get rid of a lot of the problems you bring
up.  Youtube for example wouldn't rate a video stream as good if the packet
loss were high because it's actually looking at the bit rate of
successfully delivered encapsulated video frames I _think_ the same is true
of Netflix though they also offer a real time test as well which frankly
isn't as helpful for monitoring but getting a quick test to the Netflix
node you'd normally use can be nice in some cases.
