How to fix Microsoft Sentinel not working
Microsoft Sentinel is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:
Your browser tries to reach microsoft.com over your own connection, right now. Nothing is sent to us or stored.
Check the workspace and permissions
Open the Azure portal and go to Microsoft Sentinel. Pick the workspace tied to your subscription or tenant, then check your role under Access control (IAM); the Microsoft Sentinel Reader role lets you view incidents and logs, while Contributor lets you change rules and connectors.
Reconnect the data connector
In the service, open Configuration > Data connectors and select the connector that feeds your logs. Read the status line; if it says disconnected or shows no recent data, rerun the connector setup and confirm the credentials and API permissions.
Query the logs for recent events
Open Logs in the workspace and run a simple query for the table your connector writes to, such as SecurityEvent, CommonSecurityLog, SigninLogs, or AzureActivity. A query that returns no rows in a recent time range points to ingestion or the connector, so check workspace usage and the connector status again.
Trace the automation rule and playbook
If incidents show up but a playbook does not run, open Configuration > Automation and check the automation rule condition and playbook action. Then open the Logic App run history. Permission errors or expired API connections stop the flow.
While Microsoft Sentinel is down: what to use instead
- Logs in the Log Analytics workspace Your Sentinel data lives in the underlying Log Analytics workspace, so you can open Logs in the Azure portal and run your KQL hunting queries there when the Sentinel blades won't load.
- Microsoft Defender portal If your workspace is onboarded to the unified security operations platform, the Defender portal shows your incidents and advanced hunting, which helps when only the Azure portal view is failing.
- PowerShell or the REST API When the portal hangs, the Az.SecurityInsights module can still list and update incidents.
- Azure Monitor log alerts A few log search alert rules on the same workspace, wired to an action group, can keep paging your team if analytics rules stop firing for a while.

What happens when Microsoft Sentinel goes down
Microsoft Sentinel is a cloud-native SIEM and SOAR platform that security operations teams use to collect logs, detect threats, automate responses, and coordinate investigations. An outage interrupts data ingestion and incident creation, then stalls hunting queries and playbooks.
During an outage, connectors may stop sending logs to the workspace, so new events do not appear in hunting queries or workbooks. Analytics rules can fail to evaluate, which means incidents do not generate even when matching events arrive; automation rules and playbooks then have nothing to trigger. The first signs often show in ingestion delays or missing incidents, while dashboards refresh with stale data. Problems are frequently partial or regional, affecting one workspace or one region while other parts of the service continue.

Checked from our server in Frankfurt, Germany, 2 days ago, for www.microsoft.com. A service behind a CDN answers from many data centres, usually the one nearest to you, so these addresses are where its traffic enters, not where its own servers stand. Visitors elsewhere may see different addresses.
Checked from 11 places around the world
None of check-host.net's 11 servers got an answer from www.microsoft.com (connection timed out), but our own check from Frankfurt did, 2 days ago. That usually means the site drops automated checks from those servers, not that it is down.

How we track Microsoft Sentinel
The status on this page comes from user-submitted problem reports for Microsoft Sentinel, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Microsoft Sentinel, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.
When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. This is separate from Microsoft Sentinel's official status page: user reports tend to show a problem early, while the official page confirms the cause. If the two disagree, check both.
