You'd think Netflix would learn by now to move back to their own gear. EDIT: Downvote away; its practically dogma on HN to use AWS. How much downtime are people willing to tolerate for a "superior" technology? Sure, Amazon AWS has some great ideas and tech, but you might as well give up if your business depends on EBS in us-east-1 at all
Unless my memories of their business model are incorrect, you pay a subscription fee for access to their stuff. Same as their competitors; in the case of the one I know best, the DirectTV my parents use, heavy rain knocks out their K band based transmission systems. Cable companies are also known for providing something less that 5 9s uptime.
Netfilix might be quite willing to accept these occasional outages for what else they perceive AWS proving them.
