We run a chunk on OVH too. It is over 100X cheaper than AWS.
We have had some issues though. OVH had two major outages in the last two years. Our strategy has been to build a more robust distributed architecture and use these issues to be "antifragile," which improves our product while as still saving money.
Over time I expect OVH to become more solid as they mature.
You should get some boxes from other EU vendors as well. Don't put all your eggs in the same basket. Unless your work load is very unpredictable I don't see why people use AWS, "serverless" and platform lockin.
From what I remember one of those outages wasn't connected with network hardware/their architecture but with their new electricity feed system, after which they posted post mortem and wrote about steps that they will take so this will not happen again.
Every major platform had outages in the last 2 years - Amazon many times, google cloud also.
