So what's the big deal? It was only half an hour, right?

Bigger than you think
Before you go thinking this is much ado about nothing, let's do a little back-of-the-napkin math.

A few weeks ago, Amazon told investors to expect third-quarter net sales in the range of $15.45 billion to $17.15 billion. For simplicity's sake, let's take the midpoint of that guidance and assume Amazon expects third-quarter sales of $16.3 billion.

But that number was for total net sales -- which includes both products and services -- and most reports seem to indicate the majority of Amazon's supplementary "services" remained functional, most notably including their Amazon Web Services division, through which they manage content and traffic for thousands of other websites around the world.

As a result, and noting that around 82% of Amazon's total net revenue so far this year has come from product sales, that means roughly $13.37 billion of the company's total expected third-quarter revenue should come from the "products" category.

Next, including July, August, and September, we know there are 92 days in the current quarter -- that's 2,208 hours, or 132,480 minutes. Divide Amazon's expected $13.37 billion in net revenue by that last number, and we see Amazon is expecting around $100,920 in product sales, on average, each and every minute during this three-month period.

All told, that means a 30-minute outage for the company's main retail site would cost Amazon more than $3 million in sales. Forty minutes? That'll run more than $4 million.

Come to think of it, those numbers could be even higher considering this particular outage happened to occur smack dab in the middle of the shopping day.

Foolish takeaway
As it stands, the cause of the outage remains unclear, and Amazon hasn't responded to inquiries on the topic just yet.

But while three to four million bucks certainly does seem like a lot of money, it's hardly going to break the bank for this retail juggernaut. I suppose, then, we should try to remember "minor" outages here and there are par for the course for Web-centric beasts like

So in the end, apart from doing everything in their power to ensure their primary revenue source doesn't stay down for long, I still doubt the folks at Amazon are particularly concerned about yesterday's short-lived debacle.

So where is hoping to make the most money down the road? The tech world has been thrown into chaos as the biggest titans invade one another's turf.
