Cellar performance degradation in Paris region

Ongoing since 07:53 AM UTC, affecting Cellar.

identified Oct 27, 2026, 07:53 AM UTC

We are observing degraded performance on Cellar S3-compatible object storage in our Paris (PAR) region since Oct 27, 2026 around 07:50 UTC. Some write requests may be slower than usual and a small number may time out. The cause has been identified: our storage cluster is rebalancing data after a capacity extension and is rebuilding data from a failed disk. We are taking measures to reduce the impact of this operation. The service remains available and no data has been lost.
