netcup servers are known for their high reliability. However, sometimes network problems can still occur. If you are experiencing:
These could be indicators of issues. In this case, we recommend checking with MTR and the rescue system.
If booting via the rescue system is not possible even after a longer wait, please contact support directly with this information, your customer number, and the server name and/or IP address
Boot your server into the rescue system. You can find the rescue system in the Server Control Panel (SCP) under "Media -> Rescue System".
Your server IP may be found under "Network" in the SCP.
Use MTR (My Traceroute) or WIN-MTR to check if there is packet loss on the route to the nodes. Please carry out at least 500 pings on both the server and the corresponding host using the following terminal command:
mtr <server_ip>
Next, run Iperf3 via Terminal. This provides us with information about the connection to and from your server:
iperf3 -c speedtest.wtnet.de -p 5200 -P 10 -4
Then, execute this command:
iperf3 -c speedtest.wtnet.de -p 5200 -P 10 -4 -R
iperf3 -c speedtest.wtnet.de -p 5200 -P 10 -6
Then, execute this command:
iperf3 -c speedtest.wtnet.de -p 5200 -P 10 -6 -R
Get in touch with our support. The ticket should include:
To assist us in processing your ticket, please provide the data output by MTR and Iperf3 as a text file attachment. We will then process your request as quickly as possible.
