Incident Report

Summary AI Generated

Mixpanel's Query API experienced degraded performance for 27.6 hours, causing increased latency, slow-loading reports, incomplete query results, query errors, and data discrepancies primarily affecting US region projects. The incident was identified and a fix was implemented, with recovery progressing in phases as missing data was gradually restored to affected projects. The issue was fully resolved after engineers completed the recovery process and confirmed normal query latency and success rates.

We are experiencing degraded performance with our Query API, including increased latency. You may see slow-loading reports, incomplete query results, query errors, or data discrepancies. We appreciate your patience while our engineers work to restore normal functionality. We will post progress updates on our status page. If you have any questions, please contact support.

We've continued to make progress on the issue affecting some US projects. Query success rates have returned to normal levels, and the related processing delays have also recovered.
A subset of affected projects may still see incomplete data in query results while our recovery process runs. We're actively working on this and will share another update in 2 hours.
Impact remains limited to our US region. We do not currently believe any data has been permanently lost.
