First time accepted submitter Brandon Butler writes "Amazon.com, the multi-billion online retail website, experienced an outage of unknown proportions on Thursday afternoon. Rumblings of an Amazon.com outage began popping up on Twitter at about 2:40 PM ET. Multiple attempts to access the site around 3:15 PM ET on Thursday were met with the message: 'Http/1.1 Service Unavailable.' By 3:30 PM ET the site appeared to be back online for at least some users. How big of a deal is an hour-long Amazon outage? Amazon.com's latest earnings report showed that the company makes about $10.8 billion per quarter, or about $118 million per day and $4.9 million per hour."
