Get out the diapers. Online shopping has grown like a weed in recent years. But on Monday, when its site went missing for several hours, Motley Fool Stock Advisor recommendation (NASDAQ:AMZN) gave us a startling reminder that the key players, like bladder-busting toddlers, are still prone to the occasional accident.

In a report at ZDNet, Web performance monitor Keynote Systems said the e-commerce giant started experiencing problems yesterday morning at 8 a.m. Pacific time and that outages continued intermittently through 2:30 p.m. Pacific. It wasn't clear whether the site was the target of a deliberate attack or the victim of an internal glitch. Either way, the timing stinks.

Amazon blacked out after online retailers had a banner Black Friday. The day after Thanksgiving -- known for its ability to put retailers "in the black" -- was a huge success as online shoppers booked more than $250 million in sales, up 41% from last year, according to researcher comScore Media Metrix. Shoppers even got out on turkey day, stuffing virtual shopping carts with $133 million in goods. That's double last year's total.

The good news is that last month's shopping could account for only 17% of expected online retail sales this season, according to a research report compiled by Goldman Sachs (NYSE:GS), Nielsen/NetRatings, and pollster Harris Interactive (NASDAQ:HPOL). No doubt Amazon would get much of the remaining business, so long as its virtual doors remain open. It's worth noting that the company is expecting a windfall: Fourth-quarter guidance calls for revenue of $2.29 billion to $2.54 billion, or growth of as much as 31% over last year.

Will it now be harder for Amazon to make its numbers? Probably. But investors shouldn't overreact the way Wall Streeters did when Wal-Mart's (NYSE:WMT) Thanksgiving hiccup came to light. If anything, Foolish stock pickers ought to be looking to profit if smaller online retailers such as Motley Fool Rule Breakers recommendation (NASDAQ:OSTK) or Motley Fool Hidden Gems pick RedEnvelope (NASDAQ:REDE) see their shares spark and sputter on Amazon's blackout.

For related Foolishness:

  • Speaking of sparks, Amazon's sales have been electrifying, though some shoppers probably were more interested in its holiday pi.
  • eBay (NASDAQ:EBAY) began celebrating the season in traditional retail fashion: with a catalog.
  • Black Friday was a shade of gray this year.
