The pain begins when you need support. Just like you, I have lost a lot of sleep over domains held hostage by their incompetence (for almost a year in one instance). Lesson learned, never use OVH for domains.
The support for their dedicated servers is just as bad, mind you, but short of a hardware failure you really don't need them. I have several years of uptime on all my current services.
So for personal projects their vps/dedicated is still a fantastic value.
Well except that time one of their datacenters burned down, likely due to insufficient fire suppression, and they kept the data backups in the same building as the originals so they were also lost.

These reports criticize OVHcloud for having no fire prevention system and no power cut-off on the site, for using wooden floors, and for a free-cooling design that created airflows that spread the fire. The reports also say that water was detected near electrical systems before the fire broke out.
It takes quite a while to regain trust after shitting the bed that badly.
I asked that question Hetzner support and they admitted doing the same
the OVH contract relating to automatic backup stipulates that a backup of the VPS server is scheduled daily, exported, and then replicated three times before being available in the customer space, and that the storage space allocated to the 'back-up option is physically isolated from the infrastructure in which the VPS server is set up.'
As you mentioned I would stay away from them for things like domain hosting. Just use them for cheap compute, etc.
Neither has ever caused me a problem that didn't feel like "potentially having this level of problem occasionally is entirely in keeping with how little I'm paying" basically.
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.
Personal anecdote. A few years ago, I lost a lot of sleep on a domain renewal at OVH. Their incompetence was mind-boggling. A less common tld was the only slightly challenging bit. After a week of calling and emailing, and on the verge of the domain lapsing, I gave up and sent someone to the tld registry with cash.
Also, do search for OVH SBG2 should you have missed that.
