The cloud computing world is in crisis and its a good thing for everyone in the long term.

100% uptime is possible, and it's possible today. Nobody complains that their torrents are ever "down".

So to correct: 100% uptime is not possible... with a central point of failure such as a datacenter.

Fair enough. I should clarify that it is not impossible, only impossible for now with our existing structures. I think we will get there.

Except Netflix weathered this well... those sites just didn't build their infrastructure out to handle this.

I think "feasible" is more of the discussion. Interesting how we learned during the 08 financial crisis that everything is correlated in a crash... I think there are similarities to the cloud, Black Swan fat tails if you will.

I thought about including some mention of this. I'm sure Amazon though this specific crisis as a six-sigma event. Taleb points out in the book Black Swan, the sum of all possible six-sigma events happens a lot more often.

Ironically enough, I have an... interesting service provider at this location who aggressively throttles peer connections. I've been using torrific as a workaround, which, in turn, uses AWS.

So yes. My torrents are "down".

Your torrents aren't "down". In the same sense that having a theoretical crappy ISP that blocks GMail doesn't mean your GMail is "down".

When we talk about downtime we usually mean a global outage, for most everyone.

That's what happened at Amazon. This never happens for an active torrent. And it's all by design.

Twitter goes down all the time, sure, facebook has dropped off, yeah...

But neither of these things have ever happened for a full day. If twitter goes out, refreshing a few times (this was true even a couple of years ago when the downtime was really bad) usually lets you get through. The worst I remember seeing was a few hours down.

Same goes for facebook. The worst I can recall right now is part of the oauth system bailing out for a few hours.

AWS going out like this is an entirely different disaster. Not only was it down for an entire day, but there were a ton of eggs in the basket.

I expect large companies will rethink scalability and not put all eggs in one basket.

While I agree this is a good thing, the central issue in my mind is that AWS lead a lot of folks to believe that spanning their application across multiple availability zones was a way to protect against AWS's own failures. They spoke at YC a few months back and recommended this as a primary strategy for dealing with failure. None of their engineers or staff recommended spanning applications across different physical locations.

When all of the dust settles on this mess, thats the one question I'll be demanding from AWS. Also, how will they prevent multiple AZ's from going down simultaneously in the future?

Some of this is evolving, but if it turns out AWS mislead people you are right.

because it didn't happen with me.

How much do organizations such as Amazon, Facebook, Twitter, Hacker News etc. plan ahead for holidays such as Christmas, Easter, Thanksgiving, Mother's Day, or the last day of school, first day of University?

It seems most outages could at least be predicted somewhat just by looking at "cultural patterns", for lack of a better phrase, from my perspective a lot of outages seem to occur during the events I mentioned.

Add to that most people and resources may not be available as much or as quickly during the days when it's busier making it even more likely something will happen.
