If you were wondering what caused that outage of Netflix on Chrismas Eve, just as you were ready to watch some Christmas specials, it turned out, the problem was caused by an accidental deletion of data on the Amazon Web Service.
Amazon posted a summary of the events that led up to the outage which started at 3:24pm EST. Amazon says that the number of its subscribers that were affected were limited to those on the East Coast using a service that counted on the Amazon Elastic Load Balancing Service. And that only a small portion of those using ELB service were affected.
The data deletion was caused by a maintenance process run accidentally by one of the few developers with access to this area and the mistake was not noticed right away. It took some time to find the root of the problem. Accidents do happen.
