The Port speed (for example 1 Gbit/s) defines the maximum speed you can use for transferring data to and from your server. This is basically how fast the Network Interface Card in your Dedicated Server (or virtualized part of it in VPS and VDS) can transfer data. This should not be confused with a Unlimited Bandwidth. Should you require that, please check our Networking Add-Ons. By default, we guarantee Unlimited Traffic at an average of 100 Mbit/s to and from your server. For more details, please have a look at the specific terms of our offers.
