Three common reasons: • A real Microsoft Defender XDR incident that hasn't been acknowledged on their public status page yet — vendor status pages are updated manually and typically lag the first customer reports by 10–30 minutes. • A regional or account-scoped issue affecting a subset of customers — these rarely trigger a global status-page change. • A local problem: ISP / DNS / your own software. Try reproducing from a mobile data connection and from a different network to isolate. If you suspect a real Microsoft Defender XDR issue that isn't reflected yet, contact their support to escalate. Subscribing here means you get the alert the moment they do post an update.

We use Microsoft Defender XDR's own status page at https://status.office365.com and cross-reference their homepage (https://www.microsoft.com/en-us/security/business/siem-and-xdr/microsoft-defender-xdr). Nothing is read in a way the vendor hasn't explicitly made public — we use the same data their own dashboard uses. So our data is as accurate as what you'd see loading the status page yourself, but rolled into one dashboard alongside every other service you depend on.

All tracked Microsoft Defender XDR components are reporting operational. No incidents are currently affecting service.
