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.
