Re: [Bus. Ops] Hosting Akamai FWIW the topic of NetFlix servers was covered very recently here: »Netflix CDN Server
I suppose it would be ideal if you could get some kind of report from NetFlix et al to see exactly what videos and content are watched/consumed, and how many times/how much from your IP ranges. This would probably give you an indication of whether caching will present any kind of value to your network.
