Some of you are commenting that asking OVH to randomly restart customer servers would be silly. I agree.
My comment was about servers managed by OVH. The post-mortem specifically says: "Since then, we have been working on restarting services. Powering the site with energy allows the servers to be restarted, but the services running on the servers still need to be restarted. That's why each service has been coming back gradually since 10:30 am. Our monitoring system allows us to know the list of servers that have successfully started up and those that still have a problem. We intervene on each of these servers to identify and solve the problem that prevents it from restarting."
The language used suggests that these are servers monitored and operated by OVH, not by random customers.
OVH monitors customers' servers and investigates if they stop responding to pings, unless you opt out of this. I'm guessing they were looking at this system to make sure all their customers' machines came online again after the incident.
