1) Facebook is powered by massive infrastructure which can be only be compared to likes of Google. Visa, Mastercard are too small even to be compared.

2) People at Facebook are Smart - as Facebook hired top talent. those "hackers@Facebook" know their sh!t & together they are better prepared that any of us here for thwarting ddos attacks.

so my message to annon is: Kids, Please don't understand facebook's infrastructure & the smart people who work there.
