Care to give a summary so I don't have to give them personal details?

  Stop trying to put conversion engagement trickers out of a job. Give them all your personal information so they can send you drip emails over the next six months to sell you things.

  No real info in there. They only say that they mix CDNs based on where the different strength, probably using some DNS tricks of their own based on GeoIP. No real details on how they figured how to split things or how they performed the split itself.

""" At the highest level, a “balanced” CDN architecture is one that leverages two or more CDNs hosting identical content to increase (a) the overall number of physical Points of Presence for the network (PoPs) and (b) the proximity of those PoPs to the end users accessing them around the world """

Unfortunately that whitepaper says nothing on how they do it. My theory is that they're using the Dynect CDN manager. This is a tool created by Dyn to let companies use their DNS system to pick which CDNs are used where, and to create round robin rules that are percentage and region based. I confirmed this by checking their nameservers, which are currently pointed at Dyn (ie, NS1.P24.DYNECT.NET). The thing that amuses me about this is that Edgecast offers this same service at a far, far more reasonable price. I'm not sure why they didn't just use them.
