What alternatives are there? Not many good ones at a comparable price point. (Yeah I know about online.net, Hetzner and so on. OVH offers a much more polished product and vastly better network)
At the prices OVH offers, you can have your servers replicated in multiple datacenters for less money than many DCs would charge you for a single server with the same specs.
At this price point it should be perfectly fine if a datacenter burns down occasionally. At least their network is otherwise very reliable.
