> Isn't this the company that is trying to get rid of 25% of their employees?
Just clarifying this in general, when a company makes a voluntary offer to some segment of employees, especially at this size, it is a statistics game of how many people accept the buy out.
They did not make the offer to 25% of the employees to downsize by 25%, they did it to downsize by 5% (or something like that), and then made the offer based on how many they expect to accept. This is specifically covered in this line of the geekwire article:
> Microsoft didn’t provide a projection for how many employees will accept, but the company told GeekWire it anticipates a much smaller share than the roughly 30% who took its earlier voluntary retirement offer, which went to longtime employees more likely to take the deal.
They probably expect 10-20% of those offered to take it, which would result in a 2.5-5% total downsizing.

Aside: What with the nature of the Teams, OneDrive, etc, products being Sharepoint and Exchange in a trenchcoat this is probably creating quite a mess for services besides Exchange Online, too.
Edit: Looks like the status page needs a status page.
Edit: Verified w/ multiple other parties that Teams and OneDrive are having issues, too. Interestingly, Microsoft 365 Family services are working fine. That makes me wonder if that product is running on separate infrastructure (or just hasn't caught fire yet).
That was never the promise. The nearest to that is the promise of multi-cloud or hybrid infrastructure, but neither of those have anything to do with outages of specific Microsoft services.
This usually isn't a software quality issue, it's overcomplicated infrastructure failures cascading through a complex environment causing additional systems to fall over.
DDOS?
Status page is down. Much of our org is halted.
Fingers crossed that Azure isn't impacted (seems fine so far)

And with Google is people complaining Chrome doesn't load their "pages". I bet they mean outlook.

The biggest site I work for, who went M365 hybrid last year, has incurred more Exchange downtime today than they had all of last year.
That is a software issue.
Service quality is in better hands after the layoffs, at least that’s what investors are led to believe.
