   Starting June 9 at 20:55 UTC, ingestion delays affected accounts on app.us1.dataset.com and app.eu1.dataset.com. The issue was identified, and a hotfix was deployed on June 10 at approximately 08:00 UTC. Ingestion has returned to normal in the EU environment. We are currently processing the remaining backlog in the US environment to restore normal performance.

2. 2026년 6월 11일 PM 4:37 UTCresolved

   As of June 11 at 8:11 UTC, the backlog events for accounts on app.us1.dataset.com have been completely processed, and the incident has been resolved.

   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 this issue.

2. 2025년 1월 16일 PM 7:10 UTCinvestigating

   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. 2025년 1월 16일 PM 7:48 UTCidentified

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

4. 2025년 1월 16일 PM 10:01 UTCmonitoring

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

5. 2025년 1월 17일 AM 12:22 UTCresolved

   The backlog data caused by the incident has been fully recovered in all regions

   We are currently investigating the issue.

2. 2024년 10월 24일 PM 5:13 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. 2024년 10월 24일 PM 6:11 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. 2024년 10월 24일 PM 7:11 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.
