We serve a high volume of requests per second on certain OVH servers for a specific service, with continuous monitoring enabled. While their network didn’t maintain flawless uptime every second of the year, it achieved approximately 99.999% availability based on our observations, which is enough for us. However, we don't rely on their fully managed cloud services (databases, data platform, their containers etc), but we use their LBs, network services etc and as to servers we prefer solutions that are closer to bare metal. So we can’t speak for all of their services, only the ones we’ve used and have experience with.
I'm curious, though: Do you have monitoring set up for your OVH machine? Because I've noticed that very often, disruption may just be short and not necessarily noticeable unless you happen to use the service at the time. But for something critical (or a website for your business), this is still a problem.
One of the services I used was Migadu. I migrated away from them after three months because they were just constantly unavailable for short periods of time. It was really annoying. Looking at their status page, you can see disruptions quite often. Of course, I can't say whether that's OVH's fault, or Migadu's, or a mix of both:

Edit: The other service I used was masto.host. Just checked his social media account, and the last incident was two months ago: https://mastodon.social/@mastohost/114350904325778343 - If you scroll down on his profile, you'll see more posts like this, quite frequently.
