The status page reports that defender, DLP and others are now affected. This could get really ugly really fast.

Neither email nor Teams is working at my non-tech megacorp employer. Wonder how much of the economy this is impacting.

Teams has been working all day for me but I haven't been able to use outlook (app, not web) for about 7 hours now. Fortune 20 company, BTW.

Same for me. Status won’t load even.

Personally I kinda enjoy these outages…

Isn't this the company that is trying to get rid of 25% of their employees?

Status page is down. Much of our org is halted.

Fingers crossed that Azure isn't impacted (seems fine so far)

> 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.

Why do they offer these buy outs at all, doesn't the US have at will employment?

Or is this just a gesture of goodwill to avoid people jumping the ship on their own?

tesin 4 hours ago|||
At will applies on a one by one basis - at a certain headcount, WARN legislation applies https://www.dol.gov/agencies/eta/layoffs/warn

And the other part is the "goodwill" you mention - if you jettison people for nothin en masse, word gets out, and make it hard to hire in the future

NotMichaelBay 4 hours ago||||
I think both parties probably benefit; people who are more likely to take the offer are those who have another reason to leave (unfulfilled, etc). This will benefit the company in the long run because they can eventually replace them with someone who want to join (people applying for the job).
ifwinterco 4 hours ago||
Can go the other way though: people who've been there for a while, are motivated and back themselves to get another job will take redundancy (i.e. the people you want to keep).

People who aren't motivated and/or don't back themselves to get another job will stay (i.e. probably the people you want to get rid of)

Voluntary reductions do not have the same reporting requirements or protections that actual layoffs have.
gmane 4 hours ago||||
If you lay people off, you’re on the hook for their unemployment. A voluntary buyout avoids that, and also avoids mandatory reporting for layoffs.
evenhash 3 hours ago||
That’s not entirely accurate. Washington State pays unemployment, not the company. The state funds unemployment by taxing payrolls, but it’s much more indirect than most people think.

Claims do affect the rate they pay next year, but the company isn’t “on the hook” for you personally, at least not any more than they are for your social security income.

coredog64 4 hours ago||||
A layoff of any real size has negative impacts to their unemployment insurance premiums and restricts their ability to file PERM for employees. Meeting those targets with voluntary separation prevents those impacts.

You can at will fire but that doesnt stop lawsuits. Most of these require signing docs to get the payout. It is a way to cut cleanly and derisk the cut

The speed of change has accelerated drastically at some organizations, so even if quality stayed the same, the number of outages would increase because of the # of changes has condensed to happen over much shorter time frames.

The fact that it is always Big Even Number shows how stupid it is. Imagine if it was serious like "23.5176%" then you'd know they actually did their homework on leaning up operations instead of just cutting off limbs and seeing if it can still walk or not.

https://status.cloud.microsoft/ is very slow to load.

The page is showing a "Service Degredation" for "Microsoft 365 (Business or Enterprise)"

Updates below in reverse chronological order:

From the Thurdsay, November 12, 2026 at 7:30:36 PM UTC update:

Current status: We're aggressively pursuing all pathways to reduce impact. As a precaution, we've paused all deployments and configuration changes while we review recent changes for any correlation to this event. We've determined that the elevated load isn't driven by an overall increase in traffic, but by a large number of servers being unexpectedly unavailable, which is shifting load onto the remaining infrastructure. We're investigating what's causing these servers to become unavailable while we work to safely return them to service.

From the Thurdsay, November 12, 2026 at 7:16:03 PM UTC update:

Current status: We're aggressively pursuing all pathways to reduce impact. As a precaution, we've paused all deployments and configuration changes while we review recent changes for any correlation to this event. We've also moved traffic for some services off the affected infrastructure to further reduce load, with additional traffic moves in progress.

---

From the Thurdsay, November 12, 2026 at 6:59:24 PM UTC update:

Current status: We've completed redistributing connection traffic across our worldwide infrastructure, and we're moving additional traffic off the affected infrastructure to further reduce load. We're also restarting affected servers to return them to service. In parallel, we're investigating whether the elevated traffic reflects a genuine increase in requests or a shift in how traffic is being routed across our infrastructure.

From the Thursday, November 12, 2026 at 6:32:25 PM UTC update:

Title: Users may be unable to connect to multiple Microsoft 365 services

User impact: Users may be unable to connect to multiple Microsoft 365 services.

More info: Potentially impacted services include:

- Exchange Online

- Microsoft Teams

- SharePoint Online

- Microsoft Copilot 365

- Microsoft Defender XDR

Current status: We’re investigating an issue impacting multiple Microsoft 365 services and we've determined the affected infrastructure is experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors. We're restarting and repairing impacted portions of this infrastructure to restore capacity, and reviewing an unexpected increase in a specific type of service traffic to determine whether it's contributing to the elevated load. In parallel, we're evaluating options to redirect traffic to alternate infrastructure to expedite relief.

Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services.

From the Thursday, November 12, 2026 at 6:10:02 PM UTC update:

Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services.

User impact: Users may be unable to connect to their mailboxes in Exchange Online through multiple connection methods.

More info: Potentially impacted connection methods may include:

- Outlook on the web

- Messaging API (MAPI)

- Exchange ActiveSync (EAS)

- Representational State Transfer (REST) API

Current status: We’ve identified connectivity errors occurring on a portion of Exchange Online infrastructure which receives and processes users’ access requests. We’ve collected networking logs to review to further investigate the source of these errors and confirm our next steps.

Scope of impact: This issue may affect users attempting to access their mailbox in Exchange Online using the affected connection methods.

Next update by: Thursday, November 12, 2026, at 8:00 PM UTC

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).

Edit: The RSS feed seems to load fairly quickly: https://status.cloud.microsoft/api/feed/mac

I was assured that with cloud we wouldn't have a single point of failure like we did on-premise. I must have fallen asleep at my desk.

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.
EvanAnderson 5 hours ago|||
The "you can't possibly have better redundancy in your on-prem" was absolutely a sales pitch I heard to move to Microsoft 365.

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 with their on-prem Exchange servers.

moronicles 4 hours ago|||
It sounds like you are talking more about product reliability of M365 than you are about enterprise infrastructure reliability. M365 is a Microsoft product. M365 has no bearing on the credibility of cloud infrastructure as a whole, which is what your original comment spoke to.

The service has redundancy, better than individual operators could provide on-prem. From the customer standpoint though, the service as a whole is a single point of failure: it either works or it doesn't.

anyone else just watch the admin portal post an update and then roll it back to the previous update....guess it didn't work. "We've identified that affected servers are failing automated health checks, which is causing them to become unavailable, and this may be related to a recent change to a component involved in processing those checks. We're testing a configuration change on a subset of affected infrastructure to address this and, if successful, will apply it more broadly. In parallel, we've initiated a restart of all affected servers and are validating whether they're successfully returning to service." was the old message from 7:52 UTC now it rolled back to 7:30 UTC update again
