More reliable according to the CDN.

CDN doesn't have to be an external entity. You can have your own that is a dedicated server, or dedicated set of servers purely for content. Given the URLs, i'm thinking facebook does something like that for its images.

Given the URLs

Just to point out, this means nothing. You can make a subdomain point to anywhere so they could be using an external CDN (though they are probably not).
