   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 in the process of rolling back the change and restarting the affected servers. Some accounts may observe a gradual recovery of their logs.

3. 16 stycznia 2025 19:48 UTCidentified

   A misconfiguration deployment caused server resource allocation issues. A rollback and server restart have been initiated to address the problem.

4. 16 stycznia 2025 22:01 UTCmonitoring

   Recovery is currently in progress. The estimated time for full ingestion restoration is approximately 60 to 90 minutes from now.

   We are currently investigating the issue.

2. 24 października 2024 17:13 UTCidentified

   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. 24 października 2024 18:11 UTCidentified

   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. 24 października 2024 19:11 UTCmonitoring

   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.
