I'm looking at deploying "POPs" at several IDCs across the globe.
Each POP will contain several servers. (At most ten.) I would like each POP to use the same set of IP addresses; connections to these IP addresses will get to the nearest POP by virtue of routing.

Are there providers of such?
There are some ISPs and colo facilitators that work world wide. Having the same ISP AND the same data center people in each location will probably not be easy, though. And is there an important reason why you'd want to? I would advise against choosing a single network, since that will at least partially negate the advantages of "multihoming".
Will I be able to get a globally routable IP block for my AS?
For a hand full of hands full of servers? You could probably get a /24 or a /23 at most. Those are not guaranteed to be globally routable. However, you could request address space from the ISP at your main location, and announce that address space at all locations. In places where this announcement is filtered, you will still be reachable over your main ISPs aggregate.
Or is my best bet to pick one provider which has global presence?
Large ISPs are less likely to peer with smaller networks at regional exchange points. I would get a really large network as the main one and use addresses from them, and medium sized networks that peer at several regional exchange points for the other locations. Iljitsch van Beijnum
