Update August 28, 2019 JST:
That is how a post-mortem write up should look. It's got details, and they know within reasonable doubt what actually happened...
It reads like Lemony Snicket's Series of Unfortunate Events, though, lol.
Yes, it does. I'm familiar with systems of that type and the problems Amazon experienced were "rookie" mistakes. Imagine a chemical plant or even worse, a nuclear plant that made design mistakes like that. Outcome would have been a little worse than some ones and zeros getting lost.
It sure seems like rookie mistakes, doesn't it. Their system is complex, and they faced problems along every step of the way. It seems like the biggest mistake here is not actually testing procedures.
eh? It seemed like they did do test.. they just never had a failure like this in the past. Not saying there isn't room for improvement,
The blurb that @Pete-S shared doesn't say much about their testing procedures, so you could well be right. I've definitely seem cascading failures like this before where it just seems like all of the 'safeties' that you had in place would fail until things finally shut down.
That's the inherent problem with hyper-scale systems. There is no way to fully test resilience. None. Nada. Zippo. Zilch.
It's all fly by the seat of the pants theory until the sh#t statement above happens.
There is a way to full test resiliency at Hyper-Scale. But to @Pete-S 's comment about money, there's a cost to doing that kind of planning and testing and improving, and retesting. A company with a goal of purely to make as much money as humanly possible is probably not going to put enough money into a FULL resiliency test, but it can be done...

What I'm saying is that that is USELESS to end users/corporate customers...
I've been arguing that for years.
because the chances that MS's DC is going to blow up is extremely small
And yet, it is what this thread is about ... exactly that happening.

Same difference, though. Think about the number of issues that some folks have with Microsoft.

MS was US Central this year or late last.
MS was the world when their authentication mechanism went down I think it was a year or so ago.
MS was Europe offline with VMs hosed and a recovery needed. Weeks.
MS has had plenty of trials by fire.
Not one of the hyper-scale folks are trouble free.
Most of our clients have had 100% up-time across solution sets for years and in some cases we're coming up on decades. Cloud can't touch that. Period.

And no updates correct right? to have 100 % Up-time you must never do updates.

Exactly. Even the Global Stock Markets have down time for maintenance and patching.

In a cluster setting, not too difficult. In this case, 100% up-time is defined as nary a user impacted by any service or app being offline when needed.
So, point of clarification conceded.

Really, decades of uptime. Not a single bad ram module, raid failure, CPU, PSU or MB issue. No site issues (fire, earthquake, tornado etc) in all that time.

You're full of it.

I'm quite proud of our record. It's a testament to the amount of time and money put in to research, proof, and thrash the solution sets we've sold over the years. We don't sell anything we first don't proof.

So you're using technology that is at least a decade old for every one of your customers, because by your own word you can't possibly have had the time to test anything from this year and sold it to a customer!

Yes, I know you could do a cluster and that's how Cloud Providers give you that 99.9% up-time or SLA. Right now it is hard to believe no one has any issues, if cloud providers in a large scale have issues then smaller companies do have them as well. That said, no cloud provider provides any backups for anyone unless you set them up either through their offering or your company.

Not sure how that conclusion came about but far from it.
We've had plenty of NDAs over the years to proof with upcoming tech so that we're on the right page and current.

You've said you've tested everything that you sell. How could this possibly be true to make claims of decades worth of up-time. Power supplies fail, switches die, disks die, MB's die, sites lose power (which people still have jobs to do - just because the lights are out. . .)
So you're still full of it. Not to mention performing any update will eventually require a restart. Windows updates, file server migrations etc. All require some downtime.

all of those things can fail - as long as they have an HA solution that accounts for those failures.
As he said earlier - the customer has NEVER been impacted - that's the point of measurement.

Yeah and you can only fault yourself, if you are one AZ that fails. Most serious deployments are in different regions as well.
