The big problem is that OVH has an unreliable network.
It's not immediate, but many witnesses including myself, , and quite a few others had to move off of OVH because their network deteriorates within a month of buying a server.
What seems to happen is:
- you buy a server from them
- 1 month later your server is still in the same area, except now their routers/switches are failing, and they've also loaded another 1000 customers onto the same server as you
- 2 months later, the routers and switches haven't been replaced, there's probably 10,000 customers on the same physical server as you, and now you're missing blocks!
- you buy another OVH server to get around it
- turns out your "new" server got placed in the same area, now you're missing blocks again.
- you complain to OVH support, waiting a week only to get a response in French telling you that this is your fault, and that they are a budget provider and you shouldn't expect a reliable network (yes I have had a response like that before)
I happily use them for my normal web projects, irc bouncer, file server etc. - but never for witnesses. I've even stopped using them as my backup witness because I'd start missing blocks the second I flip to my backup.
These days I host my primary with (you can pay with crypto, inc. STEEM), and backup with a certain US dedicated provider.
