I really don't like how Samsung handles this.. I couldn't use my TV all morning to watch Youtube (I know, problems..), just because they think "If Samsung is down, don't bother opening the Youtube app". Seriously, what the heck...
Also, this is not the first time this happens.. I mean their data center was on fire (www.engadget.com/2014/04/20/samsung-com-outage-sds-fire/), but isn't there some failover?
