The SSO Endpoint service has resumed normal operations.
We have determined that the issue stemmed from insufficient local disk space preventing service execution. We will work to enhance our fault tolerance mechanisms to prevent recurrence of such incidents.

We have confirmed that this is caused by an internal issue within the server database.
The incident is still under investigation.

We’re having some trouble with SSO Endpoint. We’re working to fix the problem as quickly as we can. We’ll share another update shortly.
