If you do 200Mbps on a hetzner server after cloudflare caching, you are going to run out of traffic pretty rapidly. The limit is 20TB / month (which you’d reach in roughly 9 days).
One would think services like these do not have to rely on online services and have their own rack of servers. Or is this so alien these days?
Small addition: That limit applies to Hetzner Cloud servers, their dedicated servers have unlimited traffic.
You are probably talking about VMs - those do have traffic limits. Servers, on the other side, with default 1Gbit NICs doesn't (let's say until you consume 80%+ of bandwidth for months)
Quoting:

>All root servers have a dedicated 1 GBit uplink by default and with it unlimited traffic. Inclusive monthly traffic for servers with 10G uplink is 20TB. There is no bandwidth limitation. We will charge € 1 ($1.20)/TB for overusage.
