Ceph is incredibly stable and resilient.
I've run Ceph at two Fortune 50 companies since 2013 to now, and I've not lost a single production object. We've had outages, yes, but not because of Ceph, it was always something else causing cascading issues.
Today I have a few dozen clusters with over 250 PB total storage, some on hardware with spinning rust that's over 5 years old, and I sleep very well at night. I've been doing storage for a long time, and no other system, open source or enterprise, has given me such a feeling of security in knowing my data is safe.
Any time I read about a big Ceph outage, it's always a bunch of things that should have never been allowed in production, compounded by non-existent monitoring, and poor understanding of how Ceph works.
