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

Down for our whole organization as well.

The M365 status page not loading reminds me of one of my favourite Simpsons jokes: https://www.youtube.com/watch?v=3Hz2uOSdV24

Same for me. Status won’t load even. Personally I kinda enjoy these outages…

Ironically, this article is down as well.

Our Outlook doesn't work either

Down detector shows like everything is down. AWS, Azure, Office, Gmail. Everything. https://downdetector.com

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) ( https://www.geekwire.com/2026/microsoft-makes-new-voluntary-... )

Seems like URL scanning is down entirely and some intermittent failures in Sharepoint.

Anybody else was served raw text of source by default ? (gwire is down too)

Software / software service quality has been declining for a few years IMO.
