More analysis from the mega-data center wars. Includes some interesting factoids about BitTorrent and many other topics.
Of course this doesn't answer the question why Google needs so much capacity in the first place, but I have a theory on that. I think Google is building for a future they see but most of the rest of us don't. I'll go further and guess that Google is planning to build similar data centers in many states and that the two centers they are apparently preparing to build here in South Carolina are probably intended mainly to SERVE South Carolina. That's perhaps 100,000 servers for four million potential users or 40 users per server. What computing service could possibly require such resources?
The answer is pretty simple. Google intends to take over most of the functions of existing fixed networks in our lives, notably telephone and cable television.
