I can't tell you the kind of servers, but I can say that I was recently in =
Prineville, OR, where FB is building a data center (and a second data cente=
r). I was used to the ol data centers - you know, where there's raised floo=
rs, cabinets, cool air, a guard and a few guys around with some screens?=20
But this was massive. I was amazed at the size - a few city blocks long and=
a city block wide, with a transformer and power line the size of a small c=
ity. I wonder if the Feds were involved.=20

Well what's making the connection? It looks like unencrypted http, if your=
social security number and last known addresses are streaming by you shoul=
d be able to see them. It's a bit of a jump to say that FB (not that I'm p=
articularly fond of them) is spying on you from a single netstat command.
You probably clicked login with facebook for some site and it's just autolo=
gging you in or overzealous prefetching. Either way, I think we can all st=
op making tinfoil hats now...
