    Between 4:05 PM and 7:16 PM UTC, some DataSet customers may have experienced intermittent issues logging into the UI via SSO. This incident was limited strictly to the login interface; data ingestion and query capabilities were not impacted and remained fully operational throughout the event. Our engineering team has successfully mitigated the issue via a system rollback, and all SSO login services have been fully restored.

    We are currently investigating the issue.

  2. identified Oct 24, 2024, 05:13 PM UTC

    A misconfiguration deployed this morning prevented the servers from scaling up correctly. We are currently in the process of manually scaling up the servers to manage the ingestion volume effectively.

  3. identified Oct 24, 2024, 06:11 PM UTC

    The aggressive scaling out of servers led to a 500 error when loading the page due to hitting the database connection limit. We are currently in the process of scaling the servers back in, and the error should be resolved shortly.

  4. monitoring Oct 24, 2024, 07:11 PM UTC

    The UI should now be loading as expected. We have increased the database connection limit to accommodate more concurrent connections. The queue is in the process of recovering and is gradually processing the backlog of events.
