What's the reliability of kimsufi like? Did you ever have any interaction with their support staff?
The only complaint I have about it are that the relay they have between France and the US is nearly always congested during US prime time. Because of this, download speeds from my server are really slow around 8PM est. Otherwise it's great.
tl;dr Development box and not in EU? Do it! Production box and not in EU? Maybe go with Hetzner or someone domestic.
