It's the second largest site in the world and it is 100% down. Not just a region going down, the entire world.

Moreover, it's not just facebook itself, any site or app that uses signin with facebook or their oauth, nope, that is not working either.

However the main reason, is I don't know if it's ever gone down before. I certainly cannot think of a time.

Like it or hate it the Facebook site isn't just any ordinary site. Combined with the fact that its not just web access that is down, this affects all apps and sites that have Like, Follow, Recommend or Sign In integration.

It's one of the biggest sites in the world so it's a bit different.

Because it's Facebook.

I am sorry if this is ever discussed, but could someone tell me why "a man died" is a big news that we should care about?

It's all about the context, who/what/where/etc.
