Proving Gig Speed

Wed Jul 18 13:45:07 UTC 2018 will pull from multiple nodes at the same time. I think there were four streams on the one I looked at, two to the on-net OCA and two that went off-net elsewhere. One of those off-net was in the same country, but very not near.

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.
