Looking forward to the postmortem on this one and how much AI contributed to the problem and troubleshooting.
I've been saying AI hasn't been tested properly. All the showcases I see aren't really pushing it far enough and they're always things you could in theory do by searching answers online. The real value is in all the problems that cannot be solved by online search.

I do know that after introduction of AI assisted dev work in the last 2 years, SLA violations in our cloud product became a frequent occurrence - this after we had gone years without facing one. The hype train has pushed QA to the sewer.

I’m extremely curious what actual veterans could even come up with to explain the situation as it currently appears.
I’ve seen the chats about cascading failures and it’s impossible to not expect AI is involved somehow (likely brain drain and what not), but what are the options?
It sure looks like “fired everyone who knew what they were doing” but I feel like at this point you’re breaking open the check book and calling them, and even if they did that I’m assuming this shouldn’t be a “normal” event?

I can think of several scenarios that could explain the outage:
A bad antivirus pattern file can cause enormous CPU spikes. E.g.: a very inefficient regular expression with too much backtracking. This tends to get pushed out every few hours to every server, irrespective of role. Hence, "rolling back" the servers to a "known good image" doesn't help, because within a few minutes they get the pattern update anyway and die with CPU overload. (IIRC this type of issue caused a Cloudflare global outage recently.)
Similarly, someone here mentioned a very recent OpenSSL security update that also caused enormously high CPU load. These critical patches have been rolled out very quickly with minimal testing because without it, systems are very vulnerable to nation-states utilising AIs to rapidly exploit new vulnerabilities. Microsoft (probably) doesn't use OpenSSL much, but if they do, it would be everywhere because its use in layer-7 load balancers tends to be "pervasive" and hence a sweeping update can absolutely trash performance of everything in the data centre. (However, this would have been fixed by rolling back)
Most other explanations wouldn't account for the global outage.

Bringing up clusters that are getting smashed the moment they’re online because of the backed up traffic?.. is it just exchange or AD failures behind it?.. could be quite complex with the traffic waiting

That would be the status updates about isolating traffic. Still can be hard to do when half of the internet is retrying their failed requests on your servers.

It's not up to the IT department. Network effects means if you don't use MS you cannot interperate with other MS-based companies as well. So you need at least some MS integration and they are happy to sell you the rest of the stack bundled with it.

There is also another type of network effect: hiring candidates or contractors with knowledge of the MS stack is much easier than finding someone who can set up an alternative.

Speculation is a fun game, but from experience, large outages tend to hinge on complex technical details not visible to the general public and I've never once seen even veterans of consummate skill and knowledge correctly guess what happened in the headline-making outages I've been privy to.

I've seen technical discussions on this stuff. Usually it's because you have a distributed system that's build up incrementally.
You bring one system online, then the next, the next; you load balance it carefully, etc.
But in these catastrophic scenarios, those involved (AI particularly), want to bring everything up all at once and that itself causes some DDoS like attacks on internal and external systems. And that's assuming you solved whatever "unhappy" system took it down in the first place.
The thing I've see with using AI for the past 6 month is it's really too dumb about how long things take. Humans have a normal sense of how long a process will take, whether a race condition can exist (eg, 1ns vs 10s), and other time based details. Whether a log is produced before something happens or after, etc.
I've been considering adding time stamps to mine plugins to track the time, but it's sorta like you need to track it both at the start of the request, at the end of it, at the bewginning of the generation, at the end of the generation.
Anyway, AI has to be shit to use in these scenarios because it can't tell that a system takes 5 minutes to bring up, and if you bring up 10 of the same systems at the same time, they have zero capabilities against race conditoins on shared resources etc.

I know this is only tenuously related, but after a week of them making changes (starting with DKIM) and blocking third party mailservers (and this week I got my first "your IP is blocked" but when you use their request to remove they say it isn't), I hope it goes down long enough to make more people migrate away

Since Musk fired most of Twitter engineers, it seems like the prevailing thought has been that you can just trim your organization of the unnecessary workers, only accelerated by AI development. I also hope that this proves out to be disastrous for MS and the thinking goes back to hiring top people and making sure they're happy.

Do you think they actually care about their "triple-9 SLA"? Only in as much as they could use it as a marketing bullet point to sign contracts to increase revenues/profits.

And at 40$ per employee per month, with all those employees now without access to the company (auth is not working so internal apps are going to be dead to), 50% of that for one month covers less than 50 minutes of downtime if your employees work 38 hours per week for 5000$ on average (and I do hope they make at least 2x more, since this is before tax).
The loss for a random due to MS software at this point is about 1400$ per seat (but probably at least double that) and rising.
Which is why every manager should now realize that their microsoft contract can never work as a valid disaster recovery option.

I tried to bring this out of our management staff when they were going all in on a SaaS that's 99% AWS backed. The SaaS was basically as integral is email is to many businesses to their line of work, and it was required to complete the business's b2b contracts which often had a turn around date. If the SaaS goes down, they're basically sitting idle and hitting contractual deadlines.
The response was basically, "we have a uptime garuntee and will pay out for downtime". But when it's clear _all_ of their clients have the same SaaS contract garuntee and a serious enough disruption would see _every_ client needing payment back, well, it's not much of a warranty is it.
Now I'm sure the SaaS has the redundancy in their system, but AI is the next deep integration that's going to hallow out a bunch of companies because some third party is just going to have a catastrophic loss somewhere down the line.

I heard a story, which you can't attribute to me of course, I just heard it -- we had a thing (literally yesterday) where a person from M$ came selling us some AI snake oil (we are very much an azure pilled org, but not super AI pilled).
The meeting was obviously in teems, because they sold us on that already and most of the presentation the screen sharing didn't work for half the people, which generated a continued stream of office-grade jokes for the whole duration of the presentation (30 minutes or so).
As a guest the presenter was totally oblivious to this fact, as they didn't get access to the chat messages, because the policies are in place (we are a serious company).

I guess we better get used to this new normal and pray your travel day or important appointment is not going to be on an outage day, whether that's MS, Crowdstrike or else.
It's amazing how frequently the world stops for these "historical events"

Btw, this is why no one should think AI-ops is a thing yet. All the promises of powerful, hands-off AI operations, preventive fixes, etc. are just BS.

This is big for medium/large fleets: fairly good central authentication, as well as being able to set policies for machine management (GPO).
I've also heard good things about PowerShell.
That is despite Microsoft ...you do know they tried to fire the guy who created it?
This has two assumptions:
1. people who knew what they were doing were all fired. maybe they just lost touch with the system reality and outsourced too much to the shaitan;
2. if the people were to be called back they can still understand what the system become after shaitan was let loose in it

It's been 18 hours since the start of the outage. If service isn't restored in the next 18 hours (36hrs+ outage), you can get the entire fee waived.
Microsoft gives a 99.9% monthly uptime guarantee, which means maximum allowed downtime is 7hrs.
