All SQL endpoints within tenant stopped working

NotebookEnjoyer — Tue, 20 Jan 2026 15:19:22 GMT

Today, out of the blue, all SQL endpoints within one of our two tenants stopped working. Queries in the Endpoint UI fail with "A task was canceled." A brand new lakehouse is "unable to create SQL endpoint" without further info. Models don't refresh saying the credentials were invalid. (Once again I notice that Fabric error messages are utterly useless.)

Has anyone experienced something like this (or even is experiencing it currently)?

Don't tell me to raise a support ticket, I'm already doing that.

Hi NotebookEnjoyer

Thanks for reaching out to Fabric Communtiy Forum Support.

There is no evidence of a widespread Microsoft Fabric / SQL Endpoint outage today, based on all public service health sources checked. Your issue very likely is tenant‑specific, even though the symptoms look like a platform failure.

The official Fabric status page reports all services running smoothly and shows no active incidents for today.

Refer- Microsoft Fabric Status. Is Microsoft Fabric down or having an outage?

You can cross check with below points :

Check the region of the affected tenant.
Restart the SQL endpoint (if UI allows it).
Verify the identity provider.

Overall, this looks like a tenant‑specific platform issue.

It was a service failure, as noted at Microsoft Fabric service status
