However: the CDNs are just front-ending existing servers ("origin
servers"). If they have something in cache they'll be fast; if not
they have to fetch it themselves, often from the other side of the
world (further/slower than you'd get by picking a local mirror
that actually has the files).
snapshots in particular are often not going to be in their cache.
