If you aren't in one of these countries, you'll have to wait until they officially support it.
If you tried to spoof your location through something like a VPN, then it might try to work (haven't tested it), but the throughput would likely be terrible and you wouldn't have a good experience with it kicking you out all the time.
@Samardh : Always worthwhile checking some other stuff before assuming it is a server issue (which I doubt that it is, but of course I can't know for sure).
