I think working for Akamai you're looking at things in a rather CDN-centric sort of way, but shuffling bits around is a relatively small percentage of what Facebook does. Actually doing things with the data beyond serving it up takes a lot more servers. The "CDN-equivalent" servers in PoPs etc for FB are a a pretty small percentage of the total, and the bulk are things like web/cache/search/DB servers.
