I'd think they are fit for production, a few services use them, like Lichess (can see their stack here https://lichess.org/costs )
I just meant that I wouldn't recommend the 5 EUR / month dedicated servers for production: these do not have a big bandwidth and they don't have ECC RAM.
I edited my other post accordingly.
the very good DDoS protection just seems to null route YOUR ip if it receives more than a certain amount of traffic/second
for me it used to trigger a few times a year from just random internet noise, like a portscan (as no-one other than me knew the host even existed)
This is not how it works. I recommend you go to the related webpages (just type "OVH antiddos" on Google), the anti-DDoS system is well documented nowadays.
If you _actually_ suffer from "null-routing"-like issues when the anti-DDoS triggers, you might want to get in touch with the support team to escalate the issue.
I have a feeling they may be very interested about this.
Seeing their single greatest cost line-item being "site moderation" (more than developer salary!) is such a stark reminder of where the real problems running an internet service are.
