Screenshot of Hetzner object storage degraded for >1month

Object Storage in HEL1 has been partially degraded since 2026-09-09, with a subset of buckets experiencing elevated response times, stalled requests and occasional timeouts. Engineers traced the symptom to intermittent stalls in low-level commit operations that can last several seconds and affect different parts of the cluster unpredictably. The situation was temporarily contained with a workaround that brought the cluster back online, but intermittent delays continued. Increased utilization of the Object Storage product is cited as contributing to an I/O bottleneck that underlies the performance issues.

To resolve the I/O problem, Hetzner is performing background bucket migrations within HEL1; these migrations are intended to rebalance load and do not require any customer action. Updates across September and early October report ongoing monitoring, continued investigation of the root cause, and stepwise mitigation: the workaround reduced direct impact to buckets, and migrations aim to restore full performance. As of 2026-10-08 the incident remains in monitoring with occasional delays still possible for affected customers until migrations and underlying fixes are complete.
