Easy: If something is wrong with the physical gear it's OVH's problem rather than theirs. It also means no one has to ever go to the data center which is probably important for a geographically distributed team (I assume they are). Cheap, no-frills cloud is extremely underrated, IMO.
Underrated? The flip side is that hardware failures are still your problem like they would be with rolling your own hosting. I think they’re correctly rated for the position on the scale of traders that they provide.
