Their VPS hosts have a 10GBit uplink, but they offer no bandwidth guarantees per VPS and state you can expect 300-500MBit/s[1]. Their dedicated servers have a 1GBit uplink with guaranteed 1Gbit/s bandwidth.
The Hetzner Cloud ARM instances I believe are on 2.5Gb or 1Gb links. I've never been able to get > 1Gbit on the ARM instances, but easy getting it on x86_64.
Not quite correct. Their dedicated servers base configuration have 1gig. But when ordering you can add 10gig as an easy option (or add later).
The 1 gig is too cheap to meter with free traffic. If you choose 10gig you pay for the traffic. Those who need it might use it :-)
