The "organization" has the /16 but has sites spread out all over the planet and has assigned /24's to them. Additionally, they connect into the global net via diverse providers.
Ah, I got -snip- happy there :) in that case I would question the logic of being given a large address block only to break it into pieces all over the world. I'd wonder why they dont take address space from a regional provider - if its only /24 it cant be that mission critical for bgp and multihoming...
