Why is this company getting so much attention as of late? I've never heard of them until recently, and considering how crowded the whole VPS/dedicated server market is, what makes them stand out?
I've used them for a few years now. I think they used to be very much German-language focused, but over the past couple of years they have become more and more international. They give good support and the servers I have with them have been rock solid
The recent buzz is the first time I see them mentioned on US-centric sites though, if memory serves.
As for your question, it appears that many people find the price/performance ratio of the EX 4S compelling.
