Heads up on OVH I have a support ticket open since last Sunday on a dedicated server that the os wasnt installed properly, no response and now they refuse to refund my first month or respond to any of my calls/emails. A lot of reviews said their hardware and network is very good but their support is rubbish. I know my way around a server so didn't think I'd need the support! Shame they don't.
OVH does not have a signup fee. It's more attractive than Hetzner if you just need to run an experiment for 1 month. They have servers in North America, so if you're targeting US, their latencies might be better.
