I wonder how unlimited such cheap unlimited connections really are. In the simplest case insufficient capacity in the provider network might become a bottleneck. They might notice that you are the noisiest one in the whole neighboorhood and either ask more money or throttle you. Offers that are too good to be true typically don't last very long.

At 1 EUR/TB, even the instance types that pay for traffic (e.g. the 10GBit dedicated servers) hardly break the bank.

However Hetzner does not have the best peerings, so bandwidth to some locations might be worse than you'd like.

Thats true, and I didn't actually want to suggest using the cheapest server available as a singular node either.

I just wanted to put the given numbers into the scale of the cheapest baremetal servers available on the market, to illustrate that this is not an amount of data you'd have to consider for scaling. Realistically speaking, you'd want to have more then 2 nodes so you don't have to worry about rebooting/updates etc

I have quite a few servers with hetzner. I don't know what the exact criteria are but once you hit around 250TB/month per server with multiple servers for (likely) multiple months in a row then they will tell you to chill out or they will terminate. I've gotten it and I've seen a few others on lowendtalk mention it too.

I've been using hetzner for a couple years and have always used them for my high bandwidth services but I have only gotten that notice once despite being a very heavy user, and around the same time everyone else did around a year ago. Maybe they're gonna start to care? With all the price hikes and all. I ended up just getting more servers to level it all out.

I’ve run some fairly network-heavy services (900mbps+ on a 1gbps connection, 24/7) at both leaseweb and hivelocity; they never complained about the traffic
