I don't know much about this stuff, but won't that stop working if they ever decide to expand to multiple geographical sites, to reduce latency to customers in different locations? In that case, different sites can receive requests for the same repositories, and ideally each site would be able to provide read only access without synchronization, with some smarts for maintaining caches, deciding which site should 'own' each file, etc. They could roll their own logic for that, but doesn't that pretty much exactly describe the job of a distributed filesystem? So they'd end up wanting Ceph anyway, so they may as well get experience with it now.
