There have been many opportunities to consider how crucial Amazon has become to the smooth operation of the internet over the past few years.
The most recent involved a case of fat fingers.
That event occurred late last month when an Amazon employee entered an incorrect set of commands on a computer, unintentionally knocking out a large set of servers in an Amazon data center in Northern Virginia and, with it, an array of online services from other companies.
Among the many consequences of the shutdown: Users of the business messaging service Slack couldn't upload files. Photos on the technology news site The Verge didn't display. Quora, a popular question-and-answer site, couldn't be reached.
It was a rare fumble for Amazon in cloud computing, in which companies pay to run their online applications in data centers operated by big providers.
