I have heard of a number of Ceph nightmares like this. A few years back, Logos Bible Software, who has a Ceph-based content platform (a huge library of e-books with a massive amount of meta-data), was down for a week because of a cascading Ceph cluster failure.
It really doesn't speak well of the Ceph architecture. It is highly performant, but at what cost? Failures on this scale can ruin a business.
