Thank you Aaron, 
This is great. This gives an interesting insight regarding CDN as they seem to play a big role here. However, in 
general, what do you call your ISP as? A 'Heavy Inbound' or 'Mostly Inbound'? Is there any community standard about 
this ratio (having 1:10 or higher) to be treated as Heavy Inbound? Or this is just a rough estimation?

Thank you.

I run an eyeballs/isp network for about ~50,000 subscribers, and I see about 1:10 ratio at peak time.  Last night 
~4.5 gbps out, ~45 gbps in.  But, I do have local caching of 4 big name cdn cache providers, so that might alter the 
1:10 ratio I see on my actual inet links (which do not include the local cdn traffic)
 
…take Netflix for instance… I see on my local nfx cdn links, 1:100 ratio of in:out.  20 gbps inbound and .2 gbps 
outbound  (during that same timeframe as aforementioned actual inet links)
 
Numbers based on 21:00 CDT last night.
