Hetzner - DokuWiki
All dedicated servers, except for a number of older SB (auction) servers, have a Gbit uplink. This uplink is shared among multiple servers and a connection of 200 Mbit/s is guaranteed. The EX41/51, PX61 and PX91/121 server models have 1 Gbit/s guaranteed, though this is only the case when they are located in DC17 or DC21. The DX server models also have 1 Gbit/s guaranteed.
The amount of free traffic a server has is dependant on the base monthly price of the server. The following table shows the different server prices and the respective amounts of free traffic. For AX and CX servers there is a different calculation, which can be seen in the second part of the table.
|Up to € 38.99||20 TB|
|€ 39.00 to € 83.18||30 TB|
|€ 83.19 to € 251.25||50 TB|
|€ 251.26 and above||100 TB|
|AX10, 20 and 30||10 TB|
*The monthly traffic is only calculated with outgoing traffic. Incoming and internal traffic is not calculated.
If the traffic limit is exceeded then the bandwidth will be restricted to 10 Mbit/s. You will receive warning messages via email prior to reaching the limit.
This restriction to 10 Mbit/s is permanent unless one of the following two options is chosen. Please note that Option 2 can only be chosen once. If the traffic limit is exceeded a second time then only Option 1 is available.
If you expect to exceed the traffic limit on a regular basis, we can offer a permanent default connection for your server. This means that if your server crosses the traffic limit the connection will not be restricted but you will be charged € 1.17 (price plus VAT, if applicable) per additional TB. To order the permanent connection please send a support request to our "Product advice" team via the Robot, confirming the cost for the additional traffic.
If you exceeded the traffic limit once, and don't plan on exceeding it again, we can remove the restriction, though this is only possible in the following month. To request this, please send a support request to our "Product advice" team via the Robot, clearly stating the cause of the increased traffic usage and the reason it will not happen again. For example, a single application caused a lot of traffic but has now been removed.
Traffic Limit Reporting
Under the "IPs" tab of your server in the Robot you can activate traffic warnings. This system will send you emails when pre-determined limits are exceeded, giving you a handy tool that notifies you of any irregular peaks in your traffic. You can set hourly, daily and monthly limits.
Please note that this traffic warning system is in no way related to the amount of actual free traffic you have. If you do not like receiving the warning emails or are receiving too many then you can change the limits or turn the system off.
The traffic usage can be viewed online in the Robot. Simply click on "Traffic statistics" in the menu on the left and then select the IPs you want to see the traffic usage for. You can get daily, monthly and yearly overviews.
The measured values of the traffic usage are determined by the routers only after disconnecting a TCP connection. If a TCP connection exists for several hours, the total volume of this traffic will be displayed as a peak at the time of disconnection.
The traffic API is described in the Robot webservice (point 10).
