Methodology

How we collect, store and label what Microsoft publishes.

Sources

We read public endpoints only: the Microsoft 365 status page (the banner for business tenants, the consumer services and the Power Platform admin center banner), the Azure status feed, the Azure DevOps health API, GitHub's status API, the Microsoft 365 roadmap and Azure Updates. The sources page lists each endpoint, its interval and when it last answered. Our requests identify themselves as MicrosoftRadar and link to this page.

Versions and "what changed"

Microsoft edits incident text in place. Every minute we fetch each source, remove fields that change without the content changing (timestamps, build dates), and compare the rest with the last version. When the title, text, status, affected services or regions differ, we store a new version with the full text and a word-level difference from the previous one. Raw responses are archived unchanged, so every version can be checked against what the source actually returned.

Some sources give each revision its own id. We keep that id with the version. We can only record what we have seen: if Microsoft published and replaced a revision between two of our checks, we did not see it. Versions before 13 November 2026 are not available to us.

What a status means

• Operational, degraded, partial outage, major outage: as reported by the source for that component, or as the impact of an active incident Microsoft lists for the service.
• No incident listed: Microsoft's public status page for the service's product family lists no incident. This is the absence of a report, not a measurement. Problems limited to one tenant are not on public pages.
• Unknown: no source covers this service yet.

Microsoft's own words ("Service degradation", "Investigating") are shown as Microsoft wrote them next to our normalized label.

When an incident ends

If the source marks an incident resolved, we show it as resolved by the source. If a status page simply stops listing an incident (two consecutive checks), we record a final version, label it "No longer listed" and say plainly that Microsoft did not publish a resolution on that page.

Quoted text

Text from Microsoft or GitHub is quoted for reporting and archival purposes, with the source, the capture time and a link. It is never presented as ours.
