From personal experience a few years back, OVH support was one of the worst I have ever experienced in my career. Technical incompetence at multiple levels of the chain (e.g lack of understanding of how DNS works). I would never recommend it to anyone, not even my worst enemy.
I had packet loss on my server. They asked me several times to reboot my server into rescue mode and leave it there for 10+ hours until their senior technician could look into it at an unspecified time of day.
After a month of doing this 3-4 times, they finally admitted that their switch is overprovisioned and there was no ETA. This problem happened in 2 locations.
Also had a problem with the failover ip failing to move. Again they told me to reboot into rescue mode and leave it like that for hours. No fix.
I've left OVH entirely after being a customer of theirs for over 10 years.
