Great website, but what a blunder to display the results as "cards" rather than a good old table so you can scan the results rather than having to actually read it. Makes it really hard to quickly find what you're looking for...
Edit: Ironically, that website doesn't have Hetzner in their index.
That is weird indeed. But I bet you are getting Hetzner results indirectly through resellers :) (Yeah I checked one Frankfurt based datacenter named FS1 - probably for Falkenstein. They might be colo or another datacenter there of course)
