Having implemented object storage at a service provider - it's extremely rare for any customer to have 1gbit/sec sustained throughput on an account, much less a bucket.

Those that do likely will already have an actual sales rep and the means to get these restrictions lifted, with a direct line to engineering.

Hetzner certainly markets to a different crowd, which I suspect is why these limits are being put in place ahead of time. It's very difficult to design around noisy neighbor, and will take some battle tested time in production to get right for the "average Joe" style customer who won't engage engineering resources to work with a provider to avoid hot spots and impacting other customers.

I'm more concerned about bursts, not sustained throughput. When handling large files a single client can load at 1 Gbit/s if the other side supports that.

My suspicion was also that they're intentionally targeting a different crowd than S3 and focusing on their niche here.

Definitely agreed. I would be pretty surprised if this was burst capacity though. I have no insight as to how Hetzner implemented their object storage, but in general terms it's pretty difficult to ratelimit burst without adverse effects. Sustained is a lot easier to implement since you are typically having to have multiple load balancers coordinate to achieve such results. Attempting to do this at sub-minute time intervals is pretty tricky at scale.

Just got a reply from them regarding the bucket amount and permission amount limits and both are in fact beta limits. No idea about the bandwidth though.

Presumably it's built on top of their existing VPS and dedicated server boxes, which AFAIK only have 1gbit uplinks, so they'd only be able to exceed that speed when the bucket is split between multiple boxes.

Hetzner VPS hosts have 10 GBit links.

Huh you're right, they say their VPSes have 10gig but their dedicated boxes only have 1gig, even the really expensive ones. That seems backwards.

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.

We had a fleet of dedicated hetzner boxes w/10 gbit, it’s just an option you get and pay a little extra for. Generally had good performance as well.

It looks like you have to manually add a 10G uplink to dedicated boxes: https://docs.hetzner.com/robot/dedicated-server/network/10g-...

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 :-)

At the Hetzner Summit two a few weeks ago they presented the servers used for this.

I am not sure about the exact specifications anymore, but they are building dedicated servers for this with custom chassis where each server has a ton of drives and I think they each had 40 GBits networking. These are special servers that are not available to customers directly.

I'm guessing that's because it's in beta, they want to set some low limits and incrementally increase it, is my bet.
