Do not forget physical security (including, but not limited to, access control & surveillance -- different logs, 
videos, and people to control), local/municipal/state laws and regulations (e.g. fire control standards), personnel to 
manage all that sites (even third-party)... IMHO too much administrative burden. :-(

Latency matters. Also, multiple small data centers will be more expensive
than a few big ones, especially if you are planning on average load vs peak
load heat rejection models.
