Ran a middle (non entry/exit) Tor node on one of their servers, received an automated "Abuse message"...
Wrote a support ticket regarding some network architecture question, got a one-liner "not possible".
I tried but failed to sign up for one of their 3 euro/month servers a few days back in response to other HN discussion (their .uk site wont accept Australian addresses, and their .com site doesn't have those inexpensive 1G servers).
The main reason I would have got the would have been to use as a non-US based VPN endpoint. (I'm somewhat less satisfied with my DigitalOcean droplet as a VPN endpoint since Snowden's revelations.)
I'm not complaining, nor have I seen better.
They're totally horrible to deal with, unless you make minimum wage you're probably going to spend more on packets of Tylenol due to all the headaches they cause than what you're going to save.
Their ordering process is painful. Their online management interface is atrocious. Communication is poor.
It's true what they say about paying peanuts...
I'm a long time OVH customer and I can ensure you that your contract term will start only when you get your server.
As far as I know the first 1000 "3euros" servers got sold faster than they thought. Now they are building new ones. Be patient, your server is coming. ;-)
