Who Screwed The Pooch? Microsoft Everything Down

Microsoft’s public service-health page currently reports “No current issues,” and the available official information does not identify a denial-of-service attack, compromised user, or responsible individual. ^1^

Check the status for the affected account type

• Personal Outlook.com/Hotmail account: Open Microsoft’s Service Health Status site from the Outlook.com known-issues page. Microsoft specifically directs users there for Outlook.com access problems. ^2^
• Work or school Microsoft 365 account: An administrator should open Microsoft 365 admin center → Health → Service health. This dashboard provides more detailed, tenant-specific incident information than the public network-status page. ^1^

A failure that resembles traffic overload is not enough to establish a DDoS attack. Similar symptoms can result from a service deployment, routing failure, authentication issue, or regional connectivity problem. Microsoft has previously documented an Outlook.com incident in which an incomplete software rollout generated excessive internal messages and overwhelmed routing-plane servers, illustrating why the visible symptoms alone cannot establish malicious activity. ^2^

If the relevant status dashboard remains green while the problem continues, capture the exact error message, UTC timestamp, and whether it affects the web client, app, or both. For Outlook.com, select Help, enter the problem, then under Still need help? select Yes to contact support. ^3^
