In case you missed it on the DreamHost status blog, we are upgrading DreamObjects today at 10am Pacific.
The upgrade will bring the version of Ceph, the underlying storage system powering DreamObjects, to the Hammer release. The most notable new features include bucket sharding for improved support for very large buckets (new buckets only) and support for object versioning. Support for object versioning will be limited to API functionality.
During the maintenance, DreamObjects could be temporarily unavailable. However, your data stored in DreamObjects will remain safe.
Follow the progress on the maintenance on the DreamHost status blog.
