DDOS attack

[Raven2014]

As far as I know there is only one company in the world that is known to be immune to DDOS attack ... and it is Amazon. First, because Amazon is in the business of selling server so they naturally they always have a large reserve capacity. Secondly, and probably more importantly, they did the math and see that they stand to lose hundred of millions for each minutes the website is down, or even billions if it's during holiday season. I think in the past Amazon came under concentrate attack for a straight 3 days, then the attackers gave up because Amazon's servers just shrug it off. I have never heard similar thing from any other tech companies. The joke is you can't DDOS Amazon, because the massive amount of business they process at any given moment means they're already ALWAYS DDOSed by their actual customers.

But in case if anyone wondering why there is no business incentive to preemptively stop DDOS attack ... just looks at amazon to see how big such incentive needs to be.
