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.
