However, what keeps me on Linode is that they have a London datacentre with excellent peering. I've seen 9ms pings, 150 miles away. Makes for seriously fast websites (in concert with good development processes).
Hetzner responds in 31-35ms from here. That might be Good Enough™ for many applications but it's not as special.
I've never been this tempted to jump ship though. Hopefully some of these features will become industry standard.
