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:
> Traffic
>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.
Huh, this must have changed after I concluded my contract with them (several years ago).
Huh, archive.org tells me its been unlimited since at least 5 years ago, so I guess I must’ve just seen someone mention 20TB and felt it was a reasonsble limit :)
