Update timeline

  1. investigating Nov 24, 2025, 11:52 AM UTC

    We are investigating a potential issue in our S3 Object Storage

  2. monitoring Nov 24, 2025, 12:02 PM UTC

    We identified a single node experiencing degraded performance caused by a disk hardware issue. Mitigation steps have been applied. We are currently monitoring the environment to ensure all performance metrics return to expected levels.

  3. resolved Nov 24, 2025, 06:35 PM UTC

    Error rates remained low and are now below baseline. We mark this incident resolved. While the root cause - a disk failure - was addressed quickly, high concurrent traffic delayed the return to baseline error rates. We maintained an extended monitoring period to ensure full stability. We are also confident that our upcoming S3 service improvements will significantly mitigate prolonged recovery times in similar future incidents.
